Annotations
| $\mathtt{KMET}$ | The key of the solution method. | |
|---|---|---|
| $=1$ | central difference metod (default) | |
| $\mathtt{KOUT}$ | The key of the output to the binary file name.PLS. |
|
| $=0$ | only check the input data | |
| $=1$ | after each load case | |
| $=2$ | after each cycle | |
| $=3$ | only the final solution | |
| $\mathtt{NINT}$ | The division of the integration step. The default value is $10.$ | |
| $\mathtt{KTPR}$ | The key of test prints. | |
| $=0$ | none | |
| $=1$ | computation trace (recommended) | |
| $=2$ | trace + displacement vector after each iteration | |
| $=3$ | trace + reaction force vector | |
| $\mathtt{NGD}$ | The order of numerical integration on the element, $1\le\mathtt{NGD}\le4.$ The default value is $\mathtt{NG},$ i.e., the value assigned to the element in the mesh processing. | |
| $\mathtt{PENAL}$ | The spring stiffness for contact problems $[\text{N}/\text{m}^3].$ | |
| $\mathtt{TSTEP}$ | The size of the integration step for the central difference method $[\text{s}].$ | |
| $\mathtt{BETA}$ | The parameter of the special form of the Rayleigh dumping matrix $\mathbf{C}=\beta\mathbf{M}.$ | |
| $[\mathtt{IN}]$ | The list of node numbers. | |
| $\mathtt{IREC}$ | The record index number of the load case in the binary file name.SOL. |
|
| $\mathtt{ISET}$ | The set index number. | |
| $\mathtt{KPRIN}$ | The key of printing of nodal quantities in each integration step. | |
| $=1$ | displacements | |
| $=2$ | displacements and velocities | |
| $=3$ | displacements, velocities, and accelerations | |
| $\mathtt{KQT}$ | The key of initial conditions. | |
| $=1$ | initial displacements | |
| $=2$ | initial velocities | |
| $X_0,Y_0,Z_0$ | The constant initial vector in the direction of global coordinate axes. | |
| $[X]_0$ | The initial vector. The number of components (the length of the vector) must be the same as the number of degrees of freedom of the mesh. | |
