Hi, I got this message “An unexpected error occurred while preparing the model for meshing: the Boolean union of the model parts produced an invalid model. Please contact our support for assistance.” It doesn’t exactly pinpoint my problem or where I should be looking to fix it and I was wondering if I could receive any help. I was having problems already working on it beforehand and it kept leading to different forums and I am assuming I fixed those as I imprinted certain parts and removed one and changed some settings.
Hey @CCAB ,
Thanks for reporting the error message and for sharing the project link. I have forwarded it to the team. The issue is specific to your CAD and once the solver team investigates what’s wrong, we will get back to you here with an update / workaround.
Request you to not make any changes to this project and to try any workarounds on a separate (copied) project until then. 
Cheers,
Satvik
