Inhomogeneous Conditions
Inhomogeneous conditions can be defined between a *STEP card and an *END STEP card only.
First line:
- *BOUNDARY
- Enter any needed parameters and their value.
Following line:
- Node number or node set label
- First degree of freedom constrained
- Last degree of freedom constrained. This field may be left blank if only one degree of freedom is constrained.
- Actual magnitude of the prescribed displacement
Example: *BOUNDARY Nall,2,2,.1
assigns to degree of freedom two of all nodes belonging to node set Nall the value 0.1.
Example: *BOUNDARY,MASS FLOW 73,1,1,31.7
applies a mass flow rate of 31.7 to node 73. To have any effect, this node must be the midside node of a network element.
