Description

Use the solver object to access finite element method (FEM) solver settings in pcbComponent object.

Creation

Syntax

s = solver(pcbComponent)

Description

s = solver(pcbComponent) returns solver used in pcbComponent for EM analysis. For more information on EM solvers, see Overview of Solvers. After you create a solver object, you can modify object properties using dot notation.

Note

You must set SolverType property to 'FEM' in the pcbComponent object.

example

Input Arguments

expand all

pcbComponent object specified as a string.

Example: s = solver(obj) returns a solverobject.

Properties

expand all

The boundary condition of the FEM solver specified as 'perfectly-matched-layer' or 'absorbing'.

Example: p = pcbComponent(SolverType='FEM');s = solver(p);s.BoundaryShape = 'absorbing' creates a pcbComponent solver object with BoundaryCondition specified as 'absorbing'.

This example shows how to create a solver object of a pcb component object. The solver object allows the properties of the finite element (FEM) solver to be specified.

Create a PCB component object

Create a pcb component object with its solver type specified as FEM. The solver type must be specified as FEM.

p = pcbComponent;
p.SolverType = 'FEM'
p = 
  pcbComponent with properties:

              Name: 'MyPCB'
          Revision: 'v1.0'
        BoardShape: [1×1 traceRectangular]
    BoardThickness: 0.0016
            Layers: {[1×1 traceRectangular]  [1×1 dielectric]  [1×1 traceRectangular]}
        FeedFormat: 'FeedLocations'
     FeedLocations: [2×4 double]
      ViaLocations: []
       ViaDiameter: []
         Conductor: [1×1 metal]
              Tilt: 0
          TiltAxis: [0 0 1]
              Load: [1×1 lumpedElement]
        SolverType: 'FEM'
        IsShielded: 0
         Connector: [1×1 RFConnector]

Create the solver object

Create the solver object and specify the boundary condition as 'absorbing'.

s = solver(p);
s.BoundaryCondition='absorbing'
s = 
  FEM with properties:

    BoundaryCondition: 'absorbing'
