Hi barney75, compound finite rotations are computed by quaternion multiplication. The final rotation components are extracted from the resulting quaternion. See theory manual, look for quaternion parametrization. Hope this helps, potf

Hi PeterP1, Look for unsorted node sets in the manual. Once you have sorted your node list as needed, you can create a so called "unsorted node set" out of it ("unsorted" because it is not sorted by node label). As unsorted node sets are not supported by /CAE, you'll probably have to use the...

Hi mikechy, look for "compound rotations" and "quaternion parametrization" in the Abaqus user manual. Hope this helps, potf

Hi, that's exactly the purpose of the variable DTIME in the subroutine URDFIL mentioned by guru64.

Hi, I had this type of warning when rigid body motion occured. I guess that this can happen some way when a part isn't constrained anymore due to too big deformation. So make sure that none of the parts can move freely in space during the forming process. G

As I had this problem, I tried out the transformation on a very simplified model (which has actualy nothing in common with my original model) for testing purpose of the transformation function: It is a simple C3D8 cylinder under axisymmetric load, with axisymmetric mesh, nothing else. (no...

Hi, The model (a contacting part) and the load are not axisymmetric in the following steps, which are the important steps, that's why I didn't use the 2D axisymmetric elements. Unfortunately I don't think I can use the "2D axisymmetric with non axisymmetric load" elements (CAXA) here either...

Hi! My model is as follow: 3D solid, revolved, C3D8 elements, material: steel. I am trying to transform the field output of my model into a cylindrical coordinate system with CAE. Therefore I create a news CSYS in the visualisation module and in "result options" I choose transformation ->...
