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 $\mathtt{KREST}=2.$
