Calculates the electromotive force (emf), or voltage drop along a

APDL Command: EMF predefined path.


EMF invokes an ANSYS macro which calculates the electromotive force (emf), or voltage drop along a predefined path (specified with the PATH command). It is valid for both 2-D and 3-D electric field analysis or high-frequency electromagnetic field analysis. The calculated emf value is stored in the parameter EMF.

You must define a line path (via the PATH command) before issuing the EMF command macro. The macro uses calculated values of the electric field (EF), and uses path operations for the calculations. All path items are cleared when the macro finishes executing.

The EMF macro sets the “ACCURATE” mapping method and “MAT” discontinuity option on the PMAP command. The ANSYS program retains these settings after executing the macro.
