Element Forces (Vector Plot)

1D element forces and moments are supported as vectors and can be plotted using the Vector panel in HyperView.

This functionality is available for the .op2 and .xdb files. Element force and moment data is requested using the ELFORCE or FORCE case control command in Nastran and OptiStruct.

To use this functionality, load the model and results files with the Advanced Result-Math template in HyperView.
In the Vector panel, select 1D Element Forces (v) or 1D Element Moments (v) result types and click Apply to visualize the vector plot. The corresponding forces or moments vectors will plot at the centroid of 1D elements.

The 1D Element Forces (v) and 1D Element Moments (v) result types contain X, Y, Z, and magnitude components for all supported 1D element types, which allows plotting force results of multiple element types at the same time.

Supported Element Types

The supported element types and their corresponding component mapping information for forces and moments are listed below:
