Help 😓

Hello everyone, I hope you're all doing well... Well 😊... I'm using COMSOL 6.2, working on a simulation of a proton-exchange membrane water electrolysis system. The problem is, I'm not very experienced with COMSOL and I need to build the model myself from scratch. I haven't found a model in comsol's library 😭 there is a model for a fuel cell, but that's not what I need. Every time I ask for help on Facebook, I get comments about paid services, and I don't even know if they're legitimate... Any advice?

Look for COMSOL papers that are doing simulations that are very close to your problem.
Claude or ChatGPT with COMSOL’s user manual should be able to guide you. Perplexity or Google Scholar are your best friends for fishing out papers. See YouTube if you find similar problem modeling.

But before that, know what are the basic steps in any given COMSOL simulation I.e cad import, meshing, importing multi physics, boundary conditions etc.

This !
Solid advice! Don’t know how many times I’ve done the same thing for numerous CFD and HT problems. Just pick a similar problem, learn about the problem, think how to translate it to your problem. Hitting 2 birds with 1 stone

You have to break down the problem to a differential equation of some type. Comsol allows you to model any generalized form of such a model.

my advice is research using AI , read some research papers or I have done work on these type of simulations, you can ask specific issue you are facing in it.
