I have a orthotrop material and defined the material direction with tangent curves in the mesh associated data. The right side with the radius is okay but the left side and the flat parts have wrong material directions. Anyone an idea how I can modify the orientations like in the attached sketch?
I had the same problem a while ago. It is because for material orientation you can only select one curve. All the the Elements are then oriented by that curve.
Solutions are that you either:
1. partition your volumes and do orientation for every partition with a curve
2. you use a spline to modell your curve
maybe there is a way to connect curves just like you can combine surfaces, but I haven't found that on yet.
Hope that helps!
