Annotations

$\mathtt{KREST}$	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).

Note
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 $\mathtt{KREST}=2.$
