Annotations

KMETThe key of the solution method.
=1central difference metod (default)
KOUTThe key of the output to the binary file name.PLS.
=0only check the input data
=1after each load case
=2after each cycle
=3only the final solution
NINTThe division of the integration step. The default value is 10.
KTPRThe key of test prints.
=0none
=1computation trace (recommended)
=2trace + displacement vector after each iteration
=3trace + reaction force vector
NGDThe order of numerical integration on the element, 1NGD4. The default value is NG, i.e., the value assigned to the element in the mesh processing.
PENALThe spring stiffness for contact problems [N/m3].
TSTEPThe size of the integration step for the central difference method [s].
BETAThe parameter of the special form of the Rayleigh dumping matrix C=βM.
[IN]The list of node numbers.
IRECThe record index number of the load case in the binary file name.SOL.
ISETThe set index number.
KPRINThe key of printing of nodal quantities in each integration step.
=1displacements
=2displacements and velocities
=3displacements, velocities, and accelerations
KQTThe key of initial conditions.
=1initial displacements
=2initial velocities
X0,Y0,Z0The constant initial vector in the direction of global coordinate axes.
[X]0The 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.
