Special Mesh Properties - Fixpoints
Mesh Global PropertiesSpecialsFixpoints
Fix- and density points at the ends of straight
lines
With this selection, the generator will search
for straight edges in your structure that are parallel to the mesh lines
and will create fixpoints and density points at their ends.
Fixpoints at center of elliptical lines
This selection lets the generator search for
any circular or elliptical edges in your model. For every edge found the
generator attempts to set a fixpoint in its origin.
Fixpoints at ellipse bounds for ellipse diameter
larger than...
With this setting, the generator searches for
any elliptical or circular edges in your structure that are parallel to
a mesh plane. The largest radius of the edge is then checked against a
given limit. If the radius exceeds this limit, fixpoints are generated
for the edge at its extreme positions along the coordinate directions.
The limit is specified as a fraction of the base mesh-step size (the default
step size due to the Lines
per wavelength and Lower Mesh Limit settings).
If the edge radius becomes larger than the specified fraction of this
base step, fixpoints will be created for the edge.
Fixpoints for wires
This selection lets the generator search for
any starting points or endpoints of wires and discrete ports and attempts
to set a fixpoint there. This option should be switched on if discrete
ports are used. Discrete ports are always mapped to the mesh. Therefore,
if there are no mesh nodes where the starting points and endpoints of
the ports are located, these points will be shifted to the next mesh node.
Fixpoints at probe center points and 2D field
monitor planes
This selection enhances the accuracy of probes
and 2D field monitors.
Fixpoints inside shapes with less than
Use this setting to avoid a very dense and irregular
mesh when dealing with large structures and lots of details. For these
structures, only fixpoints at the bounding box will be generated.
Merge fixpoints on thin PEC and lossy metal sheets
With this option, two very close mesh lines
on thin metal sheets can be avoided. This saves simulation time, but has
the same accuracy due to the PBA technology.
Generate fix- and density points for background
material
Create fixpoints
and density points for the background
material of the calculation domain.
