Convergence errors in Abaqus, Overclosure issue, (Interactions in Abaqus Part - 03) 

This how a FEM tutorial should be, rather than teaching us just the software. I am just a beginner in FEM and I deeply admire your great depth of knowledge in the field.

Best video on Abaqus interactions so far. Very well explained! Thank you.

Thank You very much Sir

Sir, thanks for videos. Your videos really helps😊

Your videos are Very helpful. Please make a video on gusset plate of roof truss, actually facing problem with boundary conditions of a gusset plate welded with members. Thanks in advance.

Dear Sir its a really excellent explanation on this topic. I am new to analysis, if possible can u please do a video on the meaning of CONVERGENCE...?

Great job!!

3 nodes are used more than once as a slave node in *TIE keyword. These constraints are not removed either due to the presence of *CONSTRAINT CONTROLS,NO CHANGES keyword or because removing the constraints might affect the model. The nodes have been identified in node set ErrNodeOverconTieSlave. Can anyone help me ? why this error occurs?

Thank you for the clear explanation sir. Even I am facing this error saying 'too many increments to solve the step' while modelling an MSE wall problem. But I'm not able to rectify it. Can you please help me sir, to resolve the issue. It's my humble request

Thank you sir very much

Thanks for the video. It is very helpful for beginners like me. Can you explain the message file how to read the average force, residual force sir. It will be helpful.

For large amount of force governing equation cannot be converge. Could you please explain in detail or in another way?

Your videos is excellent, I am wondering if there are any pdf file about these content?

Excellent Tutorial...Thanks...can you explain if in case we have overclosure, how can we run the simulation with it, because, sometimes cad model is such that we cannot edit it, and, we need to work with th model given to us... So in that case how we can run simulation with over closure... Thanks...

Dear sir, I hve problem regarding redundant constraint due to multiple constraint applied in a node. The situation is the steel stud in composite beam need to be assigned by two types of constraint which "embedded region constraint" of concrete in surrounding of steel stud surface and another one is "tied constraint" btw bottom surface of steel stud to steel beam. In this case,some nodes (specifically located at toe of steel stud) hve redundant constraint and abaqus has removed the tied constraint automatically. Consequently, no longer tied constraint exist btw steel stud and beam. This is unwanted removal. Can u suggest any technique on how to ensure both constraint can be applied without any deletion of constraint by abaqus?

Sir please help me, if i want modelling rotary friction welding with dissimiliar material joint. And the result that i want is both of those material could be deformed and joint. Which one am i create with CEL concept or ALE methods on abaqus?

Thank you !!

SIR G Can you please explain the concept of using different meshing elements Hex, tet etc?

Thnks sir, How to match nodes at one point of different parts in meshing...plz can u upload vidoe of it

how about thisproblem sir "Excessive distortion at a total of 110 integration points in solid (continuum) elements" thanks ??

Thank you very for your comprehensive tutorial. I am currently modelling a compression of hollow circular shell between two plates, one fixed and one moving. the perimeter is exactly flushed with the plates during assembly but i still receive convergence error and somehow my mesh is distorted from square mesh to 3D triangular mesh when using general contact. May I ask how could i solve this problem. And with regards to self contact within the shell how would you model it to minimize the error? Thank you very much in advance.

Thank you

can you share some ideas to prevent chattering in contact

sir, I ran Holzapfel hyperelastic model and got the result. But when I run the model with UMAT I am getting this kind of error "THERE IS ZERO FORCE EVERYWHERE IN THE MODEL BASED ON THE DEFAULT CRITERION. PLEASE CHECK THE VALUE OF THE AVERAGE FORCE DURING THE CURRENT ITERATION TO VERIFY THAT THE FORCE IS SMALL ENOUGH TO BE TREATED AS ZERO. IF NOT, PLEASE USE THE SOLUTION CONTROLS TO RESET THE CRITERION FOR ZERO FORCE." sir, where is the problem and what should I do?

I have a Question The thumbnail of this video has errors and warnings that are not described in the video. Is it incomplete??

I have two channel sections connected back to back to form an I Beam, which means I have a large contact area.. I have defined the interaction as Surface to Surface with Small SLiding. But I am facing the same errors. How do I resolve the issue?

Thanks .How to make little bit adjustment for converge the solution? In non linear analysis lage quantity of mesh can not be used because it is time consuming.

During the solution of analysis, I got some error which is related to max penetration error at master and sleeve surfaces. Can you help me, are there any methods to solve these type errors. Note:I tried changing size of mesh but it didn't solve problem of max penetration errors.

Sir we are getting warning ⚠️ saying.......( solver problem.Zero pivot when processing D.O.F 4of 15 nodes)..... Help where we can correct it in which part

Sir in 16.16 How to change the orientation of the master surface please reply me sir...

Sir, My ABAQUS simulation aborted due to some errors. But I could not find any message files in the folder. Is there any way to get message file?

Sir, I'm getting an error in Abaqus as "Time increment required is less than the minimum specified" and then the analysis gets aborted. How can I solve this problem.

can you please make video on WarnNodeBCincorret DOF and specify *preprint ,contact=yes error related video

Can i contact you sir

hello, please check your email i send you question there due my abaqus problem

Thank you very much sir
