The calculation of the effective properties forPCB properties is done automatically in Autodesk Simulation CFD based on the user inputs shown in the table below:
| User Input | Equation Symbol |
| Total Thickness | HTotal |
| Dielectric Material | KD,  , CD |
| Traces/Planes Material | Ktp,  , Ctp |
| Traces/Planes Thickness | Htp |
| Traces/Planes %Metal | Atp |
| Traces/Planes Coverage Exponent | Exp |
From this input, the effective properties are calculated according to the following expressions.
The Effective Planar Conductivity is calculated using the equation:
The Effective Normal Conductivity is calculated using the equation:
The Effective Density is calculated using the equation:
The Effective Specific Heat is calculated using the equation:
