CAD Import improvement and meshing

[timotheusruf]

in automotive we have a certain standard on cad models.

with this standard i have a lot of problems to import these files in moldflow

either it is not possible to import at all or the data results in bad meshes

with 2021 this got worse because the stl mesher does not work anymore.

moldflow says "cad file is not fine, it has errors"

i go to cad guy

cad guy tells me "cad file is very fine, there are no errors, i checked it with several volumem checkers"

i sit in the middle and the only way to go is to use alternative products like hypermesh or simlab or cad doctor which results in quite fine meshes eventually. but why is any other softeware better in handling cad models than moldflow.

since the stl mesher does not work anymore in 2021 this is step backward instead of forward.

the point is, that in automotive the standard cad quality cant be changed. in my opinion the import and meshing capability of autodesk moldflow has to change not the complete automotive industry. 

at the moment i am forced to buy alternative licenses to use moldflow properly

please improve meshing and cad model import functions.

I have wasted two days trying to get different formats from the customer that might mesh, with no success.  MPI 2021 does not allow me to use stl mesher to see where the problems are in the CAD.  CAD designer who created the model says no issues with model.  Moldflow mesher just stops.  Surface connectivity diagnostic says no issues.  Very frustrating.  Will have to go to Moldflow support to see if they can mesh in another version.
