How can I resolve assembly recognition issues in ANSYS Workbench 12?

Click For Summary

Discussion Overview

The discussion revolves around resolving assembly recognition issues in ANSYS Workbench 12 when importing parts created in Catia as IGS files. Participants address problems related to parts not being recognized, merging of contact surfaces, and potential solutions for static analysis.

Discussion Character

  • Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant reports issues with ANSYS not recognizing several parts of an assembly imported as IGS files, while others are recognized as solids.
  • Another participant suggests checking the geometry importing options in Workbench to ensure the correct settings are applied.
  • A third participant notes that using the IGS format can be unreliable and mentions the need for a CAD Interface License for Catia to improve compatibility.
  • One participant proposes that if the model lacks internal parts, it could be simplified to a beam and shell model in ANSYS Traditional, which might avoid geometry issues altogether.

Areas of Agreement / Disagreement

Participants express differing views on the reliability of the IGS format and the effectiveness of various solutions. No consensus is reached on a definitive resolution to the problems presented.

Contextual Notes

Limitations include potential dependencies on specific software versions, the need for proper licensing, and the implications of using different modeling approaches.

hi
there is an assembly of parts which i want to do static analyse on. i make the parts in cataia and import them as ''igs'' into workbench.problem 1: there are near 7 parts in my assembly which when gets into ansys , ansys doesn't recognize some of them and doesn't show them but it recognize the other parts as solids1,2,3... what can i do if i want the whole assembly in ansys ?
problem 2: instead of importing the whole , after importing some of the parts i tried to make the other parts by its geometry feature but after making the part and pressing generate ansys automatically turns the whole assembly as one parts , i mean it doesn't know the contact sufaces anymore , it automatically merge the whole contact surfaces together . what can i do?> this are the assembly pls take a lokk

check your Geometry importing option in workbench, make sure that u r checked correct importing option. me too had the same problem, sometime it shows more surface in the assembly.
 
IGS format is always a 50/50 gamble. In order to do this correctly you need a CAD Interface License for Catia.
 
In looking at the model, I am assuming that it has no internal parts and therefore, could have been done as a simple beam and shell model in ANSYS Traditional and you would have no problems with geometry since you could have created it all in ANSYS.
