I am trying to trouble shoot  a problem I am having with a kjoint2 in Radioss.  Can you help me understand the way the initial angle is outputed in the starter file?  I use two node reference systems (skew_ID1 and skew_ID2 in kjoint2 card) that have a rotation between their Z axis (see image below).  The rotation can be seen in the TH/spring (~0.5rad) when I plot it in Hyperview but I can't seem to understand how it is showed in the starter file (all numbers below 'initial angle' are 0?).  Can you help me understand the starter file info please?

    Hi,

    This is a bug in the printout of the initial angles in the starter output file *_0000.out. The angles that are printed in the /TH file are the correct ones.

    This will be fixed in the next RADIOSS version.

    Ok thank you!  I was trying to us the printout info to debug my kjoint2 problem and was getting confused because of the contradicting angle between the *_0000.out and the /TH.  I will concentrate on the /TH info.
