Example: Rigid Sliding Block in Local Coordinate System

Filename: mat_rigid.block-slide.k

Description:
A center of mass is constrained to slide along a local coordinate system.
The termination time is 0.010 seconds.

Model:
The material description references a local coordinate system to constrain the
rigid block. The rigid block is free to translate along the local z axis.

Input:
The material definition is a rigid material (*MAT_R IGID). The material
specifies the use of a local coordinate system, the local coordinate constraint
value of 100111 (tx ty tz rx ry rz), and the local coordinate system for
output. The local coordinate system specifies that the local origin is the
global origin, the local x-axis point is (1.0,0.0,1.0) and the local y-axis
point is (0.0,0.0,1.0) (*DEFINE_COORDINATE_VECTOR). A shell element is defined
in order to control the time-step.

Results:
The block slides along the local coordinate system.
