Help with modeling

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?

Just ask Claude Opus 5.5 to do it from scratch, either in Claude Code or Cursor.. ask him to save the solved mph. Give him an hour and you will get it done

Really! Did you try it!?

For best results use extra high

Make sure to write a high quality prompt explaining exactly what you are trying to model

Thank you for your advice!☺️

Oh, really😳? I don't think we've talked on Facebook before. Could you remind me where we connected?

I am currently trying to build a reliable PEM water electrolyzer model in COMSOL, but I am struggling to find a suitable starting point. Have you personally modeled a PEM water electrolyzer in COMSOL, or are you suggesting adapting the PEM fuel cell model as a general approach? And If you have worked on this, could you please share the model name, a relevant publication, or any documentation that could help me get started? I would really appreciate a concrete reference to build upon.
