i am not able to apply base excitation as i am not able to change the scope boundry condition from all bodies to base , can you please help me with this ?
Hi Sahil, you will need to set the Base Excitation field in the Details view of the Displacement boundary condition in the Transient environment to “Yes”. Please note though that if you are using a version of Ansys Mechanical older than 19.0, the Base Excitation option may not be available. If you need any additional help, please contact your support provider or reach out to us at info@simutechgroup.com to learn about our paid consulting services.
Hello and thank you for your comment! Unfortunately, Transient isn't currently supported. A multistep analysis in Static Structural is an alternative, as Transient would be much more complex to solve, and a cyclic condition would really defeat the purpose. Aside from that, we suggest you contact your Ansys support provider for further assistance. If you are interested in any of our engineering services, please email info@simutechgroup.com.

Interesting, but it seems you missing something. Maybe you were supposed to apply the initial stresses over the deformed geometry. The results that you got seems like you reached the plastic zone.
The intent of the video was to show the method for mapping stresses from an existing, solved model to another model with the same geometry. The engineer who created the video chose to map the stresses to an undeformed model. The stresses could also be mapped to a deformed model using the same methodology. The models included in the video used linear, elastic material properties. Thus, no plastic material behavior is accounted for. Should you have additional questions, please reach out to info@simutechgroup.com
Hi, i want to know the value of primary and secondary side leakage inductance. So, total leakage inductance is Lr = L11*(1-k^2). Then, how much primary side leakage inductance?

I am running a 2D transient simulation(VOF Fluent) in which vapor bubbles are generated at the bottom surface of a rectangular domain that is initially full of water with heat flux given at the bottom wall. I was trying to patch a single vapor bubble by creating a hemispherical region. I can see my volume fraction contour with the bubble after patching a hemispherical region at the bottom of the liquid. The simulation is also running perfectly when I click on "Run Calculation". When I do this same bubble patch operation through a DEFINE_INIT UDF, I can see the bubble getting patched in the vapor phase contour, but the calculation is not running. It is giving the following error in the 1st iteration itself. Divergence detected in AMG solver: vof-1 Divergence detected in AMG solver: x-momentum Divergence detected in AMG solver: y-momentum Divergence detected in AMG solver: pressure correction Divergence detected in AMG solver: pressure correction Divergence detected in AMG solver: temperature UDF code #include "udf.h" DEFINE_INIT (init2, domain1) { Message("solution initialised"); cell_t cell; Thread *cell_thread; Domain *subdomain; int phase_domain_index; //Initialisation of heater layer sub_domain_loop(subdomain, domain1, phase_domain_index) { if(DOMAIN_ID(subdomain) == 2) { thread_loop_c (cell_thread,subdomain) { begin_c_loop_all (cell,cell_thread) { real arr[ND_ND]; C_CENTROID(arr,cell,cell_thread); if (sqrt(ND_SUM(pow(arr[0],2),pow(arr[1],2), pow(arr[2],2)))<=0.00000002) { C_VOF (cell, cell_thread) = 0. ; C_P(cell, cell_thread)= 5846400; } else { C_VOF (cell, cell_thread) = 1. ; } } end_c_loop_all (cell,cell_thread); } } } } When I am running the calculation I am getting this error, but there is no error when I am patching it without udf by creating a region. I want this patching operation to be done via udf, so I can generate new bubbles after every time step in a specific pattern. (I will be using EXECUTE_AT_END for that ). I would be grateful if you can help me sir.

I am a final year Petroleum engineering student using ANSYS for my project to model slug flow/fluid flow through 90 degrees bend pipe (fluent). Please How do I setup wire mesh sensor and electrical capacitance tomography in fluent application or is supposed to be part of my geometry and if yes how go about that ?🙏🏾. I am at my wits end, I have tried everything I know but can't see the effects after simulation. Any guidance, directions or suggestions are warmly welcomed and appreciated 🙏🏾

I have a question. I am trying to build a similar model. Imagine your domain is split in half at that notch in the middle. One side of the domain will be stationary and the other side of the domain will be rotating around z axis. Although the periodic surfaces are still there, you have 2 of them which belong to the stationary fluid domain, and 2 belong to the rotating domain. Do you need to set up 2 separate periodic surfaces in fluent mesher? One matching the sides in stationary and one matching the sides in rotating domain. Or would it matter if you picked two surfaces from different domains and tag them with the same periodic surface? I am not sure if I was able to explain my question. In a nutshell, instead of 1 domain, I have 2. One rotating and one stationary. I would mesh it in workbench mesher but I am asked to use fluent mesher and I am not sure about it's capabilities

A second model could be developed, considering heating the plates before welding them and checking the final stresses after the slow cooling process of the entire joined piece. What do you think?
Hi, and thank you for your questions. Yes, that’s certainly possible. You would need to set the initial body temperature of the plates. If you were interested in any time domain effects, it would be required to run a transient thermal analysis and apply these to the structural analysis to then perform the thermal stress analysis and capture the time history of the cooling process.

Is writing the 'report definition' out after the simulation possible? I have .dat files that could check the value, but I can not find a way to write it out.
Hi and thank you for your question. Please use “Report Files” just below “Report Definition” in the project tree. In Report file you can create a file based on any Report Definition that you have created.

Good video! Just one question: at the end of the video you didn't select "intrinsic" when you imported the curve (that seems a polarization curve and not a normal curve), Oversight? Thanks for the reply.
Thanks for your comment. This is just to show how to use the sheetscan tool, but you are right: if we need to perform a demagnetization analysis for example, this has to be intrinsic. However, note that the curve should be smoothed out and start with zero to be able to assign it as intrinsic.
02:47, receiving error which generates a dump file without any details. Somehow, I can't gather original and inverse models in Workbench, where you have in system D.

Does anyone know if the student version of Ansys will let you import GDS files? My student version crashes when I try to import GDS. This is an excellent simulation software.
Thank you for the demo. Is it possible to add the pivot feature? If IGVs are there which can be rotted about its pivot, then they are subjected to have leakage flow. In that case, it is important to model the pivot in the clearance and mesh it. Is it possible to mesh this feature in new turbogrid? Also, is it possible to mesh the cooling holes in turbogrid. Thank you.
so, by change the topology to "merge", the big volume will automatically be split into 2 volumes, right? this is different from what I am struggling now
Hi, thank you for your question. Assuming you are referring to the first model shown (ie; the rectangular volume with the thin plate with the pattern of holes in it), no, the Share Topology, Merge setting does not split the volume. Using the Share Topology, Merge setting effectively imprints the hole pattern that is on the fluid volume on the left onto the fluid volume on the right once it is taken the meshing application (ie; either Ansys Workbench Meshing or Fluent Meshing).

@@SimuTechGroup i think I got the reason of my problem: share. looks like that I need to define the share tolerance in the space claim .Thank you for your reply:)
Can you give the temperature to the node? on the command ? Looking at your lecture, it seems like you can apply pressure to the node, but there is no temperature.
Hi and thanks for your questions. As a load in Mechanical, no. In the Mechanical GUI temperature loads are applied as Thermal Conditions on bodies only, as a constant temperature across the body. To apply a temperature distribution (ie; a result from a steady state thermal or transient thermal that is contained in the same Workbench project), link the Solution cell from the Steady State Thermal or Transient Thermal to the Setup cell in the Static Structural in the Project Schematic in Workbench. Temperature loads can be applied as body forces on elements via commands, not to nodes.
Is that right? Or, I think, what do you think about adopting giving the temperature according to each location from external data? I think it is the same as giving temperature to the node.@@SimuTechGroup
Hi there. In this case, the thickness of the transformer needs to be parametrized. Once the simulations are completed, the graph leakage inductance vs. the thickness can be generated by replacing the default Freq by the defined transformer thickness parameter. Hope this helps!

Thank you.I have a case like the situation in video，but needs to be applied an angular displacement.When I use the rotx command,its unit is rad or degree,and can APDL recognize the pi without any additional set?
Thank you for your questions -- First, solver units for angular displacement are always in radians. Next, APDL does not recognize the pi without any additional set. Define a parameter called ‘pi’ in the command snippet like this: pi=acos(-1) Then define your rotation in the D command as multiples of the previously defined ‘pi’ parameter. Like this: D,my_pilot,ROTZ,pi/2 (this would define 90 degrees rotation, ie; pi/2) Should you have additional questions, please direct them to info@simutechgroup.com or check out the SimuTech Skills Center: simutechgroup.com/resources/skills-center/
Thank you for your comment. Currently as of ANSYS release 2024 R1, only coordinate systems can be used to define construction geometry surfaces. To define another construction geometry surface, one needs to define, position, and orient another coordinate system.

I showed your video lecture for contact tool, and thank you very much. I have a question about a problem I have never experienced with the contact tool. When I insert a contact tool, a question mark appears in the upper left corner of the contact tool. Even if you try to delete it, it says that some paths to the contact tool cannot be found and it is not deleted. I would appreciate it if you could tell me what the cause is and possible ways to solve it. Thank you in advance

Great video, thanks... If you would like to take it one step ahead, import points into Excel, do a best fit curve, recreate points using the equation in a more uniform distribution. This prevents any non-uniform slope changes between any two points by creating a much smoother curve.
Hi my question, I am using ANSYS 2023 R2. By using RSM can I design and pre-process job in Ansys mechanical while another job being solved in the Ansys solver?
Thank you for your question! The short answer is 2 licenses are required. Using RSM doesn’t multiply your licenses - it allows you to use bigger, remote computing hardware.
