This dialog allows you to control the mesh properties
of one or more selected objects. In case of multiple selected objects
(holding down the CTRL key while selecting
a shape), the check boxes are in an undefined state such that they
are neither checked nor unchecked.
Consider
for simulation: Choose whether or not the selected shape should
be considered by the calculation.
Consider
for bounding box: Choose whether or not the selected shape should
be considered for the bounding box calculation.
Both Consider
for simulation and Consider for
bounding box settings are applied at the object level, and are
not part of mesh group settings.
Mesh group
Provide a mesh group name. Mesh groups are used
to group objects (i.e. Solids and Wires) together. They hold a set of
local mesh properties and these settings are inherited by the objects
which are part of the mesh group. If an object is removed from the mesh
group, its local mesh properties are reset to default.
Automesh and simulation settings
Mesh type: Choose
between the following choices:
Default: The default mesh type
is set in the Special Mesh Properties
Dialog.
PBA:
The most accurate Perfect Boundary Approximation庐 is recommended.
Staircase
mesh: Use the classic finite difference staircase
scheme for surface bodies or imported shapes that produce errors during
the matrix generation.
Priority: The
priority is used for two purposes: material distribution control and mesh
line control:
Material
distribution control: If the
staircase mesh or human
model is used, the material with the higher mesh priority
overwrites all other materials in each mesh cell.
Mesh
line control: The automatic mesh generation will always attempt
to avoid extremely small mesh-line distances because this would significantly
increase the simulation times. If the mesh generator has created two fixpoints
that are very close to each other, by default the mesh lines will be merged
and the resulting mesh line will be located between these two fixpoints.
However, it might be
desirable to pay more attention to an important structure detail. In these
cases, a priority for each shape can be defined.
All shapes will have
a priority of zero by default.
Whenever the automatic
mesh generator must decide to merge two mesh lines, it will choose the
location of the fixpoint from the shape with the higher
priority. Only when all fixpoints have the same priority
the mesh lines will be merged again.
Automesh
fixpoints: Choose whether or not the fixpoints
of the selected shape should be considered by the automatic mesh generation.
Consider
for refinement: Choose whether or not
the selected shape should be considered for the mesh refinement. If unchecked
selected shape will not participate in edge, face and material based refinement.
Material based refinement:
Choose whether or not the material
based refinement should be considered by the mesh generation of the selected
shape.
Snapping settings
Consider
for snapping: Choose whether or not
the selected shape should be considered for snapping.
Intervals in
x, y, z: Using this you can generate regularly spaced snapping
planes inside shape's bounding box. Let's say you have an axis-aligned
cube, and If you define 2 intervals in x, you will get an additional x-snapping
plane at the center of the cube.
Mesh refinement settings
Use
local edge refinement factor: Increases the refinement around edges
of the object by the specified factor.
Use
local volume refinement factor: Increases the refinement within
the boundary of the object by the specified factor.
Maximum mesh step width settings
Use step width
and extend range: Choose whether or not the step width and the
extend range should be considered by the mesh generation of the selected
shape.
Dx/Dy/Dz: For
structure elements of high importance for the simulation a maximum step
width for every coordinate direction can be specified. The automatic mesh
generator will not exceed this step width at the bounding box of this
structure element.
Extend x/y/z
range by: Use this setting to extend the maximum step width outside
the bounding box of this structure element by the range given.
OK
Accepts the input and closes the dialog.
Apply
Accepts the input without closing the dialog.

Closes this dialog box without performing any
further action.
