number of points in material defintion

["Michael Salloker <michael.salloker@xxxxxxxxxxxxxx>" <michael.salloker@xxxxxxxxxxxxxx>]

Hello,

I wonder how many points un B-H-curve are necessary to get a good 
description of a ferromagnetic material. 

I found out, that increasing the number of points also increase the 
speed of the calculation, so its necessary to find a sufficient large 
number of data points. 

So imagine I have a material with a saturation of about 1T, i could 
do a spacing of 0.1 T, or 0.05T aso. In general I believe its better 
to make aquidistant points for B and for H, due the nonlinearity.

Whats is the experts opnion?

Thanks

Michael
