Use of infinity box in magnetic simmulstion software.
Use of infinity box in magnetic simmulstion software.
(OP)
I am attampting to model in 3d, permanent magnetics using Cederat Flux3D. Computation takes a long time.
This is a very vague question as I am new to FEA.
Would there be any simple guidelines to sizing infinity box around magnets in order to optimise model performance?

RE: Use of infinity box in magnetic simmulstion software.
If your model has a closed or nearly closed flux path there is no need to use a really big bounding box. just 3 times the model size has very little error. Also, your mesh can become very course as you get farther out, this will help reduce solve time.
With most FEA software, it is best to start with simple course mesh, solve, refine mesh (or increase bounding box) & compare results to see if you are sufficiently accurate.
