These settings are required when growing prism mesh without an existing tetra mesh. A part name is required to assign the prism elements correctly. This can be done by typing a new name or selecting from the list of parts.
You may assign a different volume part to the prism, or add a side or top part in order to better differentiate it from the tetra region. In this case, be sure to add the prisms to the main volume part before generating output to the solver so it will be seen as one volume.
You may want to grow prisms away from the flow domain (towards the outside region). In this case, the top triangles (Top Part), as well as side quads (Side Part) must also be assigned to named parts.
- New volume part
allows you to specify a new part for prism elements, either from an existing surface or volume mesh.
- Side part
allows you to specify a part for the quad faces on the side boundaries of the prism elements.
- Top part
allows you to specify a part for the tri faces capping off the top of the last prism layer.
- Extrude into orphan region
allows you to extrude prisms away from the existing volume, instead of into it.
In Figure 278: Prisms Extruded into the Orphan Region, prism mesh was extruded from the pipe mesh region. The part STEEL_SIDE represents the metal's thickness.
