Can not import part file into STAR-CCM+




I have a simple 3D CAD model with different parameters defined as expressions, such as 'Chamfer Offset' and 'Extrude End Limit'. This is done to perform an optimazation study in STAR-CCM+. Everything works out with exporting in Simcenter NX but when I import the .prt file as 3D model I get the following error: 


Error during CAD import. Details in log file D:\...\Block.prt.log


With the following details in the log file: 

Command line : --input D:\Block.prt --output C:\Users\student\AppData\Local\Temp\661d1814-5282-424b-a5e6-3259737d6378.x_t --parasolid_pass_through --logfile D:\Block.prt.log 

HOOPS Exchange 10.2
64-bit Unicode
PK 30.0.269
ERR LoadFromFile Error -10005 D:\Block.prt


If I export the CAD model into a .STL, .STEP or .x_t it works fine but then I am losing my parameters which is the most important part of my design. Help is really much appreciated, thank you!

I would look in D:\Block.prt.log to see if any more (or more specific) errors.

I'm not sure about Star-CCM+, but in general, all the translators will remove the parameters and end up with a "dumb" solid (parameter passing is not part of the spec for the neutral formats)

Thank you for your reply.


Unfortunately, this is all the information given in the log file. So there is no more explanation of the errors..


I get your statement about parameters and 'dumb' solids. I would like to run an optimazition inside STAR-CCM+ Heeds to improve my design with parameters defined in NX (Simcenter).. 


It is possible to make different designs in NX and export as .x_t although it should also be possible to export as .prt from NX to import in Star. I do not know where this error is based on.. Thank you anyways!
