NOTE :
•If the SET is used, Grid ID and Element ID must have unique ID.
•RecurDyn does not support stress output option field and related fields.
•RecurDyn only supports interpolation element type of ‘Rotation & Translation’. So, REFC field of RBE3 is converted to ‘123456’. User cannot control this value in GUI.
•RecurDyn only supports ‘1’ as weighting factor. So, WTi field of RBE3 is converted to ‘1’. User cannot control this value in GUI.
•RecurDyn only supports translation degree of freedom in the case of independent nodes. So, Ci field of RBE3 is converted to ‘123’. User cannot control this value in GUI.
