I am trying to model a welded frame using shell elements for the bent sheet metal parts. I used the mid-plane feature in Spaceclaim to create the surfaces and then set the contacts tolerance high because the parts do not geometrically match perfectly. The solver is now giving me errors related to the contact status'.
I went so far as to re-model the assembly using surfaces in Inventor, but was still unable to get the simulation to run. I have attached the .WBPZ
Thank you!January 25, 2022 at 10:13 amAniketAnsys EmployeeAnsys staff can not download any files on the forum, so if you want to reach a larger audience to get answers from, please insert inline images describing your problem.
Also, if your model consists of shell elements, and contact between shells, have you turned on the shell thickness effect https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v212/en/wb_sim/ds_Contact_Scope.html in contact details?

Checking your geometry further, you have duplicate surfaces. Here is one snapshot:
Now I hide the last 4.76 mm surface, and there is a second surface.
You can't expect to to get a clean mesh and simulation if you have duplicate geometry in you file. Clean it up!
After you clean up, use the Share button to tie an edge to a surface. I got rid of three duplicates, there are 88 other duplicate surfaces to get rid of.
January 25, 2022 at 1:32 pmFelderSubscriberThank you all, I have been able to cleanup the surfaces. I also found that inserting mesh connections was something I wasn't doing that needed to be done.
