Volume Selector

Volume Selector mesh controls define which volumes should be meshed and how mesh should be generated. Only one instance of a volume selector mesh control is allowed.

The parameters defined for Volume Selector mesh controls are applicable to both BL + Tetra and Tetra model mesh controls.

Parameters

Parameter

Description

Select Volumes

Defines which volumes to mesh.

•	All Volumes. Meshes all of the volumes in the model. This option is also affected by the parameter Fill Void, which fills of the the voids (volume completely enclosed in another volume) when enabled.

Example: When this option is enabled, and there is a sphere inside of a larger sphere, the volume of the inner sphere as well as the volume between the two spheres will be meshed.

•	Exclude Enclosed. Meshes all of the volume except for the volumes enclosed by the defined seed node. The seed node should be enclosed in the volume.

•	Nth Largest. Select volumes to mesh based on size. Specify whether to select the 1st largest, 2nd largest, ... using the volume index "N", which is volume number. If you do not specify N, the smallest volume will be meshed by default.

•	By Seed Nodes/Elems. Select a volumes to be meshed by either specifying a seed node (the seed node should be enclosed in the volume) or touching elements. Both can be defined at same time. If there is a conflict between fluid and solid volumes, the fluid volume will take precedence.

Mesh to File

Stores the generated mesh in a .nas file after meshing is finished. When enabled, specify a location to export the mesh.

BL and Tetras in One Component

Stores BL elements and tetra elements in one component. When disabled, BL elements and tetra elements will be stored in separate components, which is useful when you need to define morphing constraints on BL elements.

Generate BL Contours

Generates a .res file in your working directory of BL result contours (Number of layers, first layer height, total BL thickness) for each input element after volume meshing is finished. This file will automatically be assigned the same name as the HyperMesh model file, but it will have a .res extension. BL contours help you visualize how BLs are generated.

View this file in the Contour panel, or by clicking File > Load > Results from the menu bar. Scroll through the available results.

Only applicable to BL + Tetra model mesh controls.
