Creating a Local Meshing

Creating a local meshing allows you to identify areas requiring a high level of detail and optimize simulation time by creating a fine mesh on specific areas only.

Note: For same meshing parameters, 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.
  1. From the Light Simulation tab, click Local Meshing .
  2. 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.
  3. 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 values 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 values therefore depend on the size of the body.
    • Select Fixed to create a meshing regardless of the size of the body or faces.
    Important: For a watertight meshing, the combination of Sag and Step modes defined as Fixed and/or Proportional to body are recommended. Beside, the meshing should be created faster than using the Proportional to Face mode.
  4. In Sag Value, define the maximum distance between a segment and the object to mesh.
  5. 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 values 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.
    Important: For a watertight meshing, the combination of Sag and Step modes defined as Fixed and/or Proportional to body are recommended. Beside, the meshing should be created faster than using the Proportional to Face mode.
  6. In Step Value, define the maximum size of a meshing triangle segment.
  7. In Angle, define the maximum angle allowed between the normals of two adjacent mesh triangles.
  8. If you want to display the current mesh 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.
