### 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

Repeat this line if needed.

    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 middle node of a fluid element.
