Many thanks ! RE: Ansys WB10.0 - cylindrical forced displacement ansysfreak (Civil/Environmental) 23 Jun 06 06:59 This still requires radial movement constraints. Use contact surfaces to enlarge the actual model. Generating a MeSH analysis grid using the MeSH Analyzer is easy: simply paste in a list of PMIDs to the. If I do the same analysis by LINE BODY method instead of solidshaft, I am not able to constraint the cylindrical support. Happy LearningSubscribe and Support Us Fix 3: 1. One approach I'm looking at, is to use a much longer cylindrical object in the tube, expand this one and Cylindrical support by selecting surface shaft ( tangential (free), radial (fixed) and axial (fixed). The best approach to the actual proces would be to radiallyĪpplying a pressure on the inside wall does not give a good result as the actual deformation is also displacement limited.
Cylindrical support ansys how to#
How to apply external forces to achieve the correct results ? The problem is that radial and tangetial deformation must be allowed and actually also the axial deformation ! So this is pretty confusing.Ģ.
You actually do not have a fixed point somewhere, but the cylindrical support might do the trick.
I expect that by doing this, the tube will get shorter and the cutouts deform.
I want to expand a metal tube with some cutouts in radial direction. Maybe I need to redefine my issue a little : The cylindrical support constraint is used for constrainingĬylindrical parts, however it does not allow you to
