Description: Defines the connections of a four-sided isoparametric solid element with four to ten grid points.
Format:
Example:
Field | Definition | Type | Default |
---|---|---|---|
EID | Element identification number. | Integer > 0 | Required |
PID | Property identification number of a PSOLID entry. | Integer > 0 | Required |
Gi | Grid point identification numbers of connection points. | Integer ≥ 0 or blank, all unique | Required |
Remarks:
The origin is located at G1 and the x-axis lies on the G1-G2 edge. The y-axis lies in the G1-G2-G3 plane and is perpendicular to the x-axis. The positive y-axis lies on the same side of the G1-G2 edge as node G3. The z-axis is orthogonal to the x and y axes.
