Comments

  1. BNDFRE1 and CSET1 are equivalent.
  2. The combination of the three ASET/ASET1, BNDFIX/BNDFIX1, and BNDFREE/BNDFRE1 are not allowed together in the same input data.
  3. If BNDFREE/BNDFRE1 and ASET/ASET1 are present, the DOFs associated with ASET will be in the B-set; except the DOF assigned to BNDFREE which will be in the C-set.
  4. If BNDFIX/BNDFIX1 and ASET/ASET1 are present, the DOFs associated with ASET would be in C-set; except the DOF assigned to BNDFIX which will be in the B-set. Any number of continuations may appear.
  5. Multiple "THRU" sequences can be used on a single card, and can span across continuation lines.
  6. If the "THRU" comment is used, G1 and G2 must exist, but the grid points between G1 and G2 are not required to exist.
