## Definition

Field Contents SI Unit Example
OPTION Rigid wall type.
= ID
Include a rigid wall identifier.
= FINITE
The rigid wall has a finite rectangular size.
= MOVING
The rigid wall is moving.
NSID Secondary node to the rigid wall.
NSEDX Secondary nodes excluded from rigid wall.
Dsearch Search distance, used when NSID = 0.

Dsearch = 1e20 Default used when secondary nodal set is not specified.

(Real)

$\left[\text{m}\right]$
XT, YT, ZT Coordinates of tail of rigid wall normal vector.

(Real)

$\left[\text{m}\right]$
XH, YH, ZH Coordinates of head of rigid wall normal vector.

(Real)

$\left[\text{m}\right]$
XHEV, YHEV, ZHEV Coordinates of edge of rigid wall vector.

(Real)

$\left[\text{m}\right]$
LENL, LENM Size of the finite rigid wall. $\left[\text{m}\right]$
Mass Mass of rigid wall. $\left[\text{kg}\right]$
V0 Initial velocity of rigid wall. In case Mass = 0 this is imposed velocity. $\left[\frac{\text{m}}{\text{s}}\right]$
