Automatic global mass matrix singularity and non-positive definite correction option. When set to ON, the global mass matrix is checked for zero or negative diagonal terms. A zero or negative diagonal term will result in the corresponding row and column being zeroed and the diagonal term replaced with BPDEFDIAG. If BPDEFDIAG is not specified (recommended), it will be calculated automatically. |
