I need to model a cylindrical tube with an elliptical opening, the problem is that I can't export what I've drawn in AutoCAD (even in SOLIDWORKS), to Abaqus (Abaqus gives an error message, saying that the opening can't be meshed). How to solve this problem? Is there a way to draw such a shape in Abaqus?
I do not have practice with Abaqus particularly, but the experience with other CAD-CAM programs, shows, that when it is required CAD models transfer from one product to another, the version of products often is important. If the version of Autotcad or Solidworks is newer than the version of Abaqus, then it is very likely the CAD models can not be recognized properly.
Good solution in your case is to try to use some of universal CAD file formats, such as *.IGS, *.STEP, *.STL, etc. (but firstly check-out what exactly universal formats supported Abaqus) that are not dependent on the version of the CAD software.
Dear Mr. Stoyan Dimitrov Slavov,
Thank you for your kind answer. I already saved the shape in such formats, however, nothing changed, the error message continues to show up.
Dear Sir,
If you could send me the original AutoCAD file to me ? You can find my email address [email protected]
I'll take a look at it and try to convert it to a suitable STEP file.
Dear Mr. John Bijnens,
I just solved this problem, thank you very much, though. I truly appreciate your kind offer to help me.
