Comments
- The identifier must be unique in each element family, but it is advised for each element type to have a unique element identifier in the global model.
- The part_ID of the tetrahedral 10-node elements must be different from:
- the part_ID of the brick element
- the part_ID of the tetrahedral 4 node element
- The values 1, 2 or 3 of the flag (Ismstr) for solid small strain formulation defined in /DEF_SOLID, are not compatible with the 10-node tetrahedral.
- Elements may be degenerated: 4 to 9 nodes.
- The 10 node tetrahedral elements are treated internally as solid elements (brick_ID), using solid materials and solid groups (grbric_ID).
- When a tetra10 element is defined as a /SURF contact segment, four triangular segments are created for each tetra10 element face.
