Planar EM Setup: Advanced Meshing Tab

Click the Advanced Meshing tab of the Add HFSS 3D Layout Solution Setup window to access the following settings.

• Circle and arc approximation: circles and arcs must be replaced with straight edge approximations before meshing. There is no attempt to match areas; points are introduced on the original arc at the locations specified by the following parameters.
• Arc step size: the angular interval below which mesh points are added.
• Starting azimuth for circles: specifies the location of the first mesh point or circles.
• Maximum number of arc points: the maximum number of mesh points on a given arc segment.
• Use arc to chord error approximation technique for arc: the resulting straight edge approximation are deviate on the original arc by more than the specified error.

Maximum arc to chord error: maximum distance permissible between a straight edge approximation (the chord) and the original arc.

• Mesh Display Attributes: controls the mesh overlay in Layout.
• Color: the mesh is drawn in the specified color; in Layout3D the layer color is used for the mesh.
• Mesh post-processing:
• Attempt to replace non-horizontal triangles with rectangles: the HFSS 3D Layout solver operates more efficiently when there are no non-horizontal triangles. With this option set, the mesher attempts to resolve all non-horizontal triangles that form a perfect rectangle into rectangular mesh elements.
