VM188 requires a supplemental .cdb input file which is too long to include full input listings. This file must be downloaded and placed in your working directory for the test case to run properly. Additionally, the geometry and mesh should be regenerated. Download link: MAPDL Test Case Files for 2024 R2 vm188.cdb |
Test Case
Two rectangular conductors, separated by centerline-to-centerline distance d, are carrying equal out-of-plane currents, I. Determine the resulting edge force density on the conductors.

Analysis Assumptions and Modeling Notes
Due to the symmetric nature of the magnetic field, a 1/4 symmetry model is generated. The far-field effects are modeled with infinite solid elements. The lower order infinite elements are meshed first so that the higher order plane elements will appropriately drop their mid-side nodes during meshing.
Lorentz forces
in the conductor are calculated for each element and are available from the
post data file. The forces are obtained from a surface integral (line integral in 2D analysis)
defined using the path calculation capabilities in POST1. Flux lines are displayed via the macro
PLF2D.
The applied source current density is calculated as 
m2 = 1 x 106
A/m2.
