Advanced DMM Object types
In order to create a DMM object with a matched surface use the "DMM Asset >> Create DMM Object Primitive" sub-menu selection or the "DMM Asset >> Create DMM Object From Polymesh" sub-menu selection. In order to create a DMM object with no input surface mesh use the "DMM Asset >> Create Bare DMM Object" sub-menu selection. In order to create a DMM object with an unmatched surface, first create a DMM object with no surface mesh (a bare DMM object), select a surface mesh and the bare DMM object and then select the "DMM Asset >> Add Surface Mesh to bare DMM Object" sub-menu item.
Here is a description of the different menu items that create DMM objects:
Menu item | DMM asset type | Description |
From Polymesh | DMM Object starting with Tet Cage | Initially, the DMM Object as a Tet Cage but no Surface Mesh |
From Triangulated Polymesh | DMM Object starting with Triangle Cage | Same as first item, only that the Tet Cage is already a triangulated mesh. The tetrahedrons triangles located on the surface will match the ones of the mesh. |
From Tetrahedral Polymesh | DMM Object starting with Tet Mesh | The mesh is already a set of tetrahedrons to be simulated as is. |
From Plane Polymesh | DMM Object starting with a plane Mesh | The mesh is a 2D polymesh. The generated Tet Mesh will be given a certain width. This is useful to create flat volumes. |
As a comparison, here is the description of the most common type (created when using primitives or when using "Create DMM Object from Polymesh" menu item).
Regular DMM Object | DMM Object starting with Surface Mesh | The DMM Object shares the same mesh for the Tet Cage and the Input Surface Mesh |
For an existing DMM Object, the DMM asset type is displayed by the Asset Manager.
