How to Build a Mesh in COMSOL Multiphysics®

[@MaheshKumar-wq6ij]

Very useful information. Thank you

Thank you for the explanation. Increasing the maximum video resolution would make it a bit more comfortable to watch, though. In particular where the text on the monitor is relevant. The narrator speaks very deliberate and is easy to understand, though. Keep her :-)

We are glad you like the video and appreciate the feedback. We will keep the video resolution and text size on screen in mind as we create more tutorial videos.

Hi, I'm new at comsol and aiming at building a cartesian PML in order to calculate the scattering cross section over a semiconductor in an specified arrange for a photoelectrochemical cell but when meshing, I fail because source and destination faces are not well defined or specified, however, I have not been able to overpass this problem since I do not understand how to make these definitions. Any idea or bibliography that explains this kind of meshing will be appreciated, thanks.

Haloo, i am working a project about generator magnet permanen in 3d right now. I have followed the instruction of guidebook in library but still cant get the voltages and magnetic flux. And i have done mesh in my model, but when i did study a warning box showed that my model hasnt mesh at all. Can you help me to figure out what happen to my model? Thank you

Why would one choose coarser mesh sizes? Doesn't finer mesh mean greater accuracy?

[@comsol]

Generally speaking, one might want to use a coarser mesh to decrease the computational resources and increase the speed of the simulation.

[@MaheshKumar-wq6ij]

It depends at what positions we want accurate results. Domain of interest should be more finer.
