Thank you very much, it seems the way to proceed. However, I am still trying to figure out how could I extract the current motion residual value for the 6-Dof implicit update option, maybe as a rp variable, to actually use it as a condition. I mean, in parameters you can extract almost any variable but I don't see how could I obtain this motion residual value.nAlternatively, as the motion is purely a 1-dof rigid rotation, I would be interested on extracting Theta_Z (which can be seen in the dynamic mesh options and can be written in a motion history file). I've tried to open the case file as a txt so I could check the rp variables names but couldn't find anything. Have you got any idea on how to deal with either of these two variables?n
