[FEMM] How to freeze the reluctivities in each element?

[Ramdane LATEB <ramdane.lateb@xxxxxxxxxxxxxxxxxxx>]

Hello, 	
I'm simulating an induction machine under a non linear field solution with 
femm and through lua language, I need to calculate all parameters of the 
machine. The idea is to determine all the parameters of the equivalent 
circuit of a specific slip frequency. For this purpose  I need to freeze 
the reluctivities of each element found from the latest non linear  field 
solutions and perform a linear FE calculation at synchronous speed with 
slip=0  (for the details see  Ping Zhou."Finite Element Analysis of 
Induction Motors Based on Computing Detailed Equivalent Circuit Parameters, 
IEEE Trans. On Magn. Vol. 34; N°.5., Sept 1998". The problem is that I 
don't know how to get the reluctivities of each element through lua (in femm).
Any idea is welcome
