Creating a local meshing allows you to identify areas requiring a high level of detail and
optimize simulation time by creating a fine meshing on specific areas only.
Note: For same values of meshing, meshing results can be
different between the CAD platforms in which Speos is integrated.
To create a Local Meshing:
Note: Only one local meshing can be applied to a geometry.
-
From the Light Simulation tab, click Local Meshing
.
-
In the 3D view, click , select the geometries on which you want to apply a local meshing and click to validate.
The selection appears in the Geometries list as linked
objects.
-
From the Sag Mode drop-down list:
- Select Proportional to Face size to create a mesh of triangles that
are proportional to the size of each face of the object. The sag and step value therefore depend
on the size of each face.
- Select Proportional to Body size to create a mesh of triangles that
are proportional to the size of the object. The sag and step value therefore depend on the size of
the body.
- Select Fixed to create a meshing regardless of the size of the body
or faces.
Note: We recommend you to apply the same mode for both Sag and Step.
-
In Sag Value, define the maximum distance between a segment and the object
to mesh.
-
From the Step Mode drop-down list:
- Select Proportional to Face size to create a mesh of triangles that
are proportional to the size of each face of the object. The sag and step value therefore depend
on the size of each face.
- Select Proportional to Body size to create a mesh of triangles that
are proportional to the size of the object.
- Select Fixed to create a mesh of triangles fixed in size regardless
of the size of the body.
Note: We recommend you to apply the same mode for both Sag and Step.
-
In Step Value, define the maximum size of a meshing triangle
segment.
-
In Angle, define the maximum angle allowed between the normals of two
adjacent mesh triangles.
-
If you want to display the current meshing properties in the 3D view, from the
Geometries list, right-click the geometry and click Preview
Meshing.
The local meshing is created and applied to the selected geometries. The
local meshing prevails over the simulation meshing properties for the selected geometries.
