Matl Command

Multiplies or divides the vector field quantity in the top register by a material property. At each tetrahedron, the field quantity is multiplied or divided by the value of the selected material property — taking the different material attributes of each object into account.

To multiply or divide a vector quantity by a material property:

1. Click Matl.

The Material Operation dialog box appears.

2. Select a property from the Material Properties list. Options include the following, depending on what solution type is assigned:

• Permeability (mu): defined as m₀m_r where m₀ is the permeability of free space

• Differential Permeability (dmu)
• Conductivity (cond)
• Permittivity (epsi)
• Mass Density: 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.
• Admittivity

3. Select an operation — Multiply or Divide.
4. Click OK to multiply or divide 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.
