Houdini 20.0 Nodes Geometry nodes

FEM Visualize geometry node

Since 16.5

This allows you to visualize various aspects of an FEM simulation. The visualization covers mesh quality, inverted tets, energy density, FEM node forces, and collision. For the visualization of an aspect to work, it is required that the corresponding attribute is generated by the FEM object that is visualized. For example, to see energy densities, it is required that Create Energy Attributes is enabled on the FEM Object.

Parameters

Type

Allow choice between visualization of mesh quality, tet inversions, energy density, FEM node forces, and collisions.

Scale

Energy Density Scale

This is a multiplier for the energy density that is used to map energy density to colors.

Power Density Scale

This is a multiplier that is used to calibrate the color range generated for energy dissipation

Force Scale

This is a multiplier that is used to compute the colors from FEM node forces

Filter

Collision Pass

When visualizing collisions, this specifies the collision pass that is visualized

Clip Interior

Enable Clip

Clip the mesh to look a visualization of the inside. Useful for sims with tet meshes.

Origin

The origin of the clipping plane

Distance

The distance of the clipping plane from the origin in the direction of the normal

Direction

The normal direction of the clipping plane
