Syntax

mesh(object)
mesh(shape)
mesh(___,Name=Value)
meshdata = mesh(___,Name=Value)

Description

mesh(object) plots the mesh used to analyze a PCB component.

mesh(shape) plots the mesh for the shapes.

mesh(___,Name=Value) changes and plots the mesh structure of a PCB component, using additional options specified by the name-value arguments. You can also determine the number of unknowns from the number of basis functions in the output.

example

meshdata = mesh(___,Name=Value) returns a mesh structure that specifies the properties used to analyze the PCB component.

Open Live Script

Create a mitered bend shape of lengths of 10 m and 2 m, width of 2 m, and rotate it about the Z-axis by 60 degrees.

bend = bendMitered(Length=[10 2],Width=[2 2],MiterDiagonal=1);
bend = rotateZ(bend,60)
bend = 
  bendMitered with properties:

              Name: 'myMiteredbend'
    ReferencePoint: [0 0]
            Length: [10 2]
             Width: [2 2]
     MiterDiagonal: 1


show(bend)

Figure contains an axes object. The axes object with xlabel x (m), ylabel y (m) contains 2 objects of type patch. These objects represent PEC, myMiteredbend.

Mesh the mitered bend shape at a maximum edge length of 1 m.

mesh(bend,MaxEdgeLength=1)

Figure contains an axes object. The axes object with xlabel x (m), ylabel y (m) contains an object of type patch.

Input Arguments

collapse all

PCB component, specified as an object handle. For complete list of PCB components and shapes, see PCB Components Catalog.

Shape created using custom elements and shape objects, specified as an object handle. For a complete list of custom shapes, see Custom Geometry and PCB Fabrication.

Example: c = bendCurved; mesh(c)

Name-Value Arguments

collapse all

Example: MaxEdgeLength=0.1

Specify optional name-value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside single quotes (''). You can specify several name and value pair arguments in any order as Name1=Value1, ..., NameN=ValueN.

Maximum edge length of triangles in mesh, specified as a positive scalar in meters. All triangles in the mesh have sides less than or equal to the MaxEdgeLength value.

Data Types: double

Smallest edge length of triangles in mesh, specified a positive scalar in meters. All triangles in the mesh have sides greater than or equal to the MinEdgeLength.

Data Types: double

Gradation in the triangle size of the mesh, specified a scalar. The default value of 0.7 states that the growth rate of the mesh is 70 percent. Growth rate values lie between 0 and 1.

Data Types: double

Customize mesh view of a PCB component, specified as a name-value argument consisting of View and 'all', 'metal','dielectric surface', or 'dielectric volume'.

You choose 'dielectric surface' to view the boundary triangle mesh of the dielectric. You choose 'dielectric volume' to view the tetrahedral volume mesh of the dielectric.

Data Types: char

Option to enable or disable plot interactivity, specified as 'on' or 'off', or as numeric or logical 1(true) or 0(false). Set this argument to 1 or 'on' to open the plot with the slicer panel, and to slice and view the desired cross section of the plot along the xy-, yz-, and xz- planes. Set this argument to 0 or 'off' to open the plot without the slicer panel.

Example: Slicer='on'

Data Types: string | logical
