Hey, I am have a bit of trouble running a simulation with a dynamic mesh where the vector field for movement is defined. It was working fine with oscillating linear and rotating motion. But not with tabulated6DoFMotion. It runs for a couple hours then throws an error message before completing the time the vectors are defined for.
This is the error message Code:
solidBodyMotionFunctions::tabulated6DoFMotion::transformation(): Time = 0.00964224 transformation: ((0.00453319 0.0616797 0) (0.95434 (0 0 0.298724)))

**update*
My flow field is crazy. The magnitude is reasonable but the direction is wack. So I thought it might have something to do with the boundary conditions. I've used freestream since it is a 2D model. Once again, Any help would be super appreciated. |

As an additional question is it possible to add a phase shift between 2 different types of motion in the multimotion parameters for the dynamic mesh?
