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. |
