Hi, Thank you for your interest in my videos. Our goal is to make High Quality Educational Videos for Students, Teachers and Researchers. All COMSOL Resources 👉bio.link/comsol ✅Available for collaborate on a Academic Research Publication & R&D
"liquid crystals" have molecular ordering that allows them to modulate light, providing image display functionality. so the working is a bit different then PC
Hi BK, how are you going? Could you explain me why do you delete the wetted wall in the multiphysics session? I have a doubt, if I'm analyzing macroscopic fluid flow of water and air, Do I need to use wetted walls?
thanks for asking! In the two-phase flow simulation (water and air), the wetted wall boundary condition is typically used when you're interested in tracking the interface between phases, especially when surface tension or wall adhesion effects are critical. So accordingly you have to decide for your work.
Hello. How can I couple the temperature field or velocity field with pde? I have a pde (it is just a concentration equation) that contains both temperature field and velocity field.
To couple temperature and velocity fields with a PDE, you'd typically use Navier-Stokes equations for the velocity field and the heat transfer equation for temperature. These can be coupled with a concentration equation using the convection-diffusion equation, where velocity advects the concentration. There maybe a video similar to the domain coming soon.. lets see
I am an Mtech student , doing my project on PCM cooling of Pv module . I dont know how to start . Is COMSOL better or Ansys for this? And what should be my approach while learning them . I have some reference research papers, which i wanna validate . Most of them used Ansys , and few used COMSOL.
The choice of software depends on a lot of parameters. Like domain, research group constants, software compatibility, study type, license etc etc. Incase you want to discuss 1:1 you can book a video meeting. (bio.link/bibhatsu)
Is it possible to define a mass transfer between two phases at those points where the volume fraction is equal to 0.5? The difficulty of the problem here is that the points where the volume fraction is 0.5 are variable and not fixed. In COMSOL, to define a flux, the boundary must be constant. Thank you for your help.
Can you please make a demo video of Laser melting simulation in Comsol, how Solid material melts and the flow like a fluid after melting using two phase flow in level set or Phase field method
Great video! I really appreciate the clear explanation. Can you please guide how to model water vapors emerging from the top into water, and how to calculate the heat and mass transfer rates. Any guidance or advice on how to approach this would be amazing! Thanks again for the valuable content! ❤
you would typically need to set up a multiphysics model that couples fluid flow with heat and mass transfer. In COMSOL, for example, you can use the Heat Transfer Module along with the Transport of Diluted Species physics to handle the mass transfer of water vapor.
Thank you. But we can not use this mehod to build a hexagonal cylinder, right? Since I apply this method to a block, and the boundary on the surface DO NOT disappear😭.
hi , brother , is you are using comsol 6.0 ? is it has wave optics ? can you check photonic logic gates can be designed and simulated using wave optics in comsol 6.0 ?
Thanks for this good and useful video.I have a question regarding plot function. Is it possible to plot a model function (Temperature, velocity, flux, etc.) using python (i.e., MPH package) ?
Hello. Can you upload a tutorial video of ferrohydrodynamics? You can have a basic laminar flow and magnetic field module to show how magnetic fluid is affected by the external magnetic field Thanks
Very nice work, I request you to work on python code to develop weak formulations and Coupling by tracking the dependent variables at point and boundaries for different components.
Thank you so much for this amazing video lecture sir. If possible can you please make some more videos related eddy current displacement sensors, l'll be deeply grateful to you sir! Thank you once again sir!
