Selecting a Physics Type
The physics type determines the default values for many of the global mesh options.
Many of the affected defaults are related to mesh sizing. An initial default size
(calc_default_size
) based on the diagonal of the selected body is
calculated, but not exposed. Meshing uses it internally to determine other size defaults as
noted in the tables below.
To select a physics type:
On the Mesh ribbon, click Physics Type.
Select Structural or Fluid Dynamics .
If you enter SpaceClaim Meshing from Ansys Workbench or Ansys Mechanical, Structural defaults are set automatically.
Option Structural Sheet Default Structural Solid Default Element shape Quadrilateral Dominant Quadrilateral Dominant, Hexahedral Blocking Standard Standard Element size 40% of calc_default_size
2 x calc_default_size
Growth rate 1.8 1.8 Curvature Off Off Minimum size (curvature) 4% of calc_default_size
4% of calc_default_size
Normal angle 30 30 Proximity Off Off Element order Quadratic Quadratic Shape checking Structural (not exposed or modifiable) Structural (not exposed or modifiable) If you enter SpaceClaim Meshing from Ansys Fluent or select Fluid Dynamics , these defaults are set automatically:
Option Fluid Dynamics Sheet Default Fluid Dynamics Solid Default Element shape Quadrilateral Dominant Quadrilateral Dominant, Hexahedral Blocking Standard Standard Element size 40% of calc_default_size
2 x calc_default_size
Growth rate 1.2 1.2 Curvature Off Off Minimum size (curvature) 4% of calc_default_size
4% of calc_default_size
Normal angle 18 18 Proximity Off Off Element order Linear (not exposed or modifiable) Linear (not exposed or modifiable) Shape checking CFD (not exposed or modifiable) CFD (not exposed or modifiable)
Alternatively, set the default physics type in the SpaceClaim Options window.
