BPDEFDIAG

Description Type Default

Mass diagonal coefficient to be used for correcting singular and non-positive definite matrixes. When AUTOBPD is 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.
