  1. The SUPORT entry specifies reference degrees-of-freedom for rigid body motion. It is not intended to be used in place of a constraint (SPCi entry or PS on the GRID entry, for example).
  2. SUPORT and/or SUPORT1 entries are required to activate inertia relief unless PARAM, INREL is specified, then SUPORT and/or SUPORT1 entries are not required.
  3. Be careful not to spell SUPORT with two Ps.
  4. Degrees-of-freedom specified on this entry cannot be defined as dependent degrees-of-freedom in rigid body element or constrained in SPCi entry or PS on the GRID entry.
  5. An alternative to SUPORT is the SUPORT1 entry, which is requested by the SUPORT1 I/O Options and Subcase Information command.
  6. This card is represented as a constraint load in HyperMesh.
