Modeller Reference Manual
 By Extrusion Enables a Volume
to be defined by extruding a
specified distance normal to a
selected Surface. The positive
direction is defined by the Surface
normal unless an additional Point
is selected. Extrusion can be
towards or away from the
specified reference Point.
Coalescing Volumes
The internal Surfaces from a Volume model may be removed by coalescing Volumes. This
will result in a model with fewer Volumes which may be meshed using Tetrahedral elements.
Case Study. Coalesce Volumes
Sometimes a results file exists without a corresponding model file. The coalesce Volumes
feature allows the results mesh to be converted to a Volume model so it can be modified
and used in a subsequent analysis.
1.
Open results file and use the File> Save As menu item to save it as .mdl file.
2.
Use Control-A to select the mesh and convert it to Volumes using the
Geometry> Volume> From Mesh menu item and select the Coalesce Volumes
option.
3.
Create a loadcase.
Delete Holes
When geometry is imported from CAD it may have small holes defined which are of no
significance in the analysis. These holes may be removed using the Geometry> Volume>
Delete Holes menu item.
Delete Voids
Voids are cavities in a Volume which do not penetrate the defining surfaces. Voids are
removed using the Geometry> Volume> Delete Voids menu item.
