CST2013: Local Mesh Property (Surface)

Mesh: Mesh Control Local Properties

(navigation tree: Groups:Mesh Groups:meshgroup1 Local Mesh Properties)
(navigation tree: Components:solid1 Local Mesh Properties)

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.

Maximum mesh step width settings

The prescribed width is an absolute value. The automatic mesh generator will not exceed this step width for this structure element. If a zero value is specified (default), it  will be ignored and the mesh size will be controlled by the global setting, see Surface Mesh Properties.  In the navigation tree, an object with a nonzero mesh step width will be signalled by  the icon, if the mesh view is active.

Local multilayer settings

Consider for local multilayer: Enable this option to allow the selected shape to be part of a local multilayer simulation (See also How to create a local multilayer setup). This option is a valid setting for thin panel material sheets which define a local multilayer layer stackup or PEC like sheets which model an antenna structure.

The thin panel sheet  needs to have a local coordinate system attached to it: Modeling: Tools Shape Tools   Local Solid Coordinates   Attach Active WCS. This is necessary to identify the direction of the layer stackup. The thin panel sheet won't get meshed. Only the PEC like structure will be meshed. The layered media will be considered automatically by using the multilayer greens function.

Reference: All shapes with the same reference belong to the same local multilayer setup. You may choose a name or accept the default. Each shape can only be part of one single local multilayer but it is possible to define several local multilayer setups.

Automatic/ Offset: This setting is valid if the thin panel shape which defines the local multilayer stackup is a curved shape. In this case you can define an offset for the antenna structure. This is helpful in case you want to ensure the antenna structure is considered to be in a certain distance to the curved thin panel shape. If left to Automatic  the offset will be determined automatically.

OK

Accepts the input and closes the dialog.
