I used sometimes this command, but in this case i didnt got find where i could use this command. If you have a little time look the file, my problem is that i did a transition with WALL>ADVANCED>BONDARIES, but there is deformation in two directions in a BONDARIE that I created., I think that the problem is in this region. Anyway i stay very glad for your attencion.
if you post your email, i can send you PTC's "Suggested Technique for Creating a Cross-Sectional Unbend" for WF2. I have to add PTC's Copyright and Trademarks notice with any material used from their site.
