Annotations

$\mathtt{KREST}$The key of restart.
$=1$assemble and eliminate the global stiffness matrix, then solve for all load cases
$=2$only solve for additional load cases
$\mathtt{KSOL}$The key of linear solution method.
$=1$direct frontal solver (default)
$=2$parallel sparse direct solver
$\mathtt{PIVAL}$The minimum allowed pivot value in the matrix factorization. The default value is $10^{-6}.$

The prerequisites for using $\mathtt{KREST}=2$ are:
i) the global stiffness matrix has already been eliminated, i.e., the program has run at least once with $\mathtt{KREST}=1,$
ii) the additionally entered load cases have already been processed with $\mathtt{KREST}=2,$
iii) the additional right-hand side vectors have already been assembled with $\mathtt{KREST}=2.$
