Radioss Warning ID 312 Incompatible Kinematic Conditions

I am getting this warning when trying to run the Radioss 2017 solver for a specific job. I have read that it can be because of a rigid body being constrained incorrectly maybe? For my model, I have a rigid body where I have constrained the master node on all DOF except translation along the Z axis. I then have applied an imposed velocity on the same node, just in the Z direction. Is this what is causing the error? If so, any recommendations on how to fix? The simulation still runs correctly, and the results seem to be correct, but I want them to be as accurate as possible, so no warnings would be ideal. I will also attach all relevant files that may be helpful.

    Hi Brandon,

    Please recheck the BC's and load in the model. As shown in the image please recheck the loads.

    Always we recommend  users to run the model checker before exporting the model, which will display the modelling errors.
