Electromagnetic Solver FPE

Fiedde1887 · November 14, 2016, 07:00

Hello,

i am running an electromagnetic solver, wich should solve a magnetic field around a copper-coil with an iron-cernel. The solution is running good, until the 10th Iteration. A FPE occurs and the Simulation stopps.
The Manual says, that a double precision-version of star should be used for magnetic fields. I am using the mixed precision-version.
Does anyone had the same Problem, becouse of the precision-version?

Thank you in advance
Nils

The Problem is lokated. We have to use the double-precision Version for magnetic-fields. Otherwise you can create a Floating-Point-error with mixed-precision.
