HFSS15: Matl Command

Operates on the vector field quantity in the top register of the Fields Calculator based on a material property. At each tetrahedron, the field quantity is operated on by the value of the selected material property — taking the different material attributes of each object into account.

To operate on a vector quantity by a material property:

1. Click Matl.

The Material Operation window appears.

2. Select a material property. Available properties are:

Permittivity (epsi)

The permittivity, er.

Permeability (mu)

The permeability, mr.

Conductivity

The conductivity, s.

Omega (w)

The angular frequency, w. The angular frequency is equal to 2pf, where f is the frequency at which the solution was generated.

MassDensity

This is based on the value of the Mass Density material property. MassDensity is treated like a named expression. Selecting MassDensity disables the Operation radio buttons for Multiply or Divide in the Material Operations dialog.


3. For Permittivity, Permeability, Conductivity or Omega, select an operation — Multiply or Divide. Selecting MassDensity disables these operations. The MassDensity scalar can be used like any other named expression.

4. Choose OK to operate on the field quantity by a material property or Cancel to stop the operation. If you selected MassDensity and click OK, a scalar named expression MassDensity is pushed onto the stack.
