| $\mathtt{KREST}$ | The key of restart. | |
|---|---|---|
| $=1$ | calculate elements’ stiffness matrices and right-hand side vectors for all load cases | |
| $=2$ | calculate only right-hand side vectors for additional load cases | |
| $\mathtt{PENAL}$ | The penalty value valid for all connection elements. The default value is $\approx10^{10}$ (it is set automatically according to local stiffness). | |
The prerequisites for using $\mathtt{KREST}=2$ are:
i) the elements’ stiffness matrices have already been calculated, i.e., the program has run at least once with $\mathtt{KREST}=1,$
ii) the additionally entered load cases have already been processed with $\mathtt{KREST}=2.$
