neat, thanks!
The academic plan comes with a much higher storage limit (50GB, see the academic plan on Plans & Pricing | Professional, Team & Enterprise | SimScale), so this should not be the reason. SimScale uses the native data you provide (in this case, the STEP file) for downstream processing (e.g. meshing) so the “data quality” is not changed withing SimScale. Depending on your CAD system, what can happen is that the STEP export does something unexpected (e.g. check on @BenLewis’s post). What exactly do you mean by poor? The tessellation of the surfaces? That might be due to optimization methods we are using to accelerate loading and interaction - but it’s just related to visualization.
Thanks for sharing the project, will look into it this week and get back to you. Once we are done, would you be fine with putting it as an example in the SimScale library? If yes, we could ask @sjoshi if he would like to join this project. He is currently working on a similar project for the library and it might be a piece of cake for him to set this up.
