You can change the unit system using the Unit System Selector or the Preferences. When importing "discrete mesh" files (.stl, .nas, .fem) with unspecified units, select the model unit in the Import Options dialog.
Use the Identify Parts tool to define types of parts like wheels, heat exchangers or body panels, which require specific modeling techniques
for the CFD run.
Baffles are used to model very thin walls, for example sheet metal parts. In the numerical surface mesh model, baffles are
represented by shell elements, which have fluid volume on both sides.
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE
studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Use the Mesh Controls tool to define regions with a
user-defined volume element size.
Important: All other mesh controls in the model are defined relative to the
far field size, and must be a power of 2 of the far field size. For example, if you
define a far field mesh size of 1 m, the available refinement sizes will be 0.5,
0.25, 0.125, etc.
Generate and Edit Box Refinement Zones
Use the Mesh Controls: Box tool to apply box shaped refinement zones around the entire body of the vehicle, or around individual parts.
Generate Part-Fitted Refinement Zones
Use a subset of the Mesh Controls: Offset tool to refine mesh based on the distance from a specific part of the model.
