I don’t really get what we’re arguing over, here. I doubt anyone’s heard of 10211 before my post on validation, and all of a sudden it’s treated like a fundamental law of physics. It’s a guide, and I’ve already explained why I did the large section and not a smaller one.
Again, unless you’ve done both 2D and 3D, you’re not really in a position to judge. That post is 6 years old. I’ve done both 2D and 3D and there can be significant differences in heat flow. Once you’re proficient in FreeCAD/meshing, you really aren’t going to save an awful lot of time doing 2D, especially with the potential errors that come with it. CAD capabilities in THERM are awful, for instance. I can’t even begin to imagine how I’d model something like this in THERM
The video is about SimScale – so what? I’ve seen that video before I found PrePoMax. As we’ve seen in the validation post that I initiated, PrePoMax is ‘valid’ for thermal bridge calculations. Why do I need to learn another FEM software when both are equally valid? And one is for free and the other is $5,000 a year.
