solver

Access FEM solver settings for electromagnetic analysis

Since R2025a

Description

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

Creation

Syntax

s = solver(pcbComponent)

Description

s = solver(pcbComponent) returns the 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 the object properties using dot notation.

Note

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

Input Arguments

pcbComponent — PCB Component

object

pcbComponent object specified as a string.

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

Properties

BoundaryCondition — FEM boundary condition

'perfectly-matched-layer' (default) | 'absorbing'

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

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

Examples

Create PCB Component Solver with Boundary Condition

This example shows how to create a solver object of a pcb component object. The solver object allows the propeties 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:

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

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'
