SKEW/MOV axes direction changing?

Hello all!

I am currently experiencing the following issue with Radioss:

In my model, there is a rigid plane that I want to rotate around a given point in a given direction. For this purpose, I have set up a SKEW/MOV in that point. The origin node coincides with this point. Here is an image of how I've set up the system (with respect to the global one):

The plane is subject to IMPVEL load (with respect to the same SKEW), where I specify a constant velocity in rad/s, in the YY direction (i want it to rotate around the Y axis of my skew).

The problem is that when I check the results in HyperView, I can see that the Z and Y axes have switched. which  means that the plane is now rotating in the completely wrong direction. 

In addition to that, it seems like it is rotating around a completely different point, instead of around the origin of the SKEW system.

If anyone knows how I can solve this or why I am encountering this problem, please let me know! All answers are much appreciated.

Thanks!

    Hello Martina,

     

    Are you using these SKEW in include format? which are grouped using SUBMODEL or using any transform cards in the model ?

    If yes, try to keep SKEW, /BC, /IMPVEL in main file and rest FE can be in include format.
