Femm releases 3.3 - 3.2

["ac090960 <ac090960@xxxxxxxx>" <ac090960@xxxxxxxx>]

Hello,

Making some trials with the new release 3.3 (downloaded today) on an 
AC axisymmetric geometry an error occurred during FKN execution: (On-
edge lamination not supported in AC analyses).
The strange is the same problem is running using the release 3.2.

The problem to be solved is composed by a steel coil (Laminated 
parallel to z, to simulate a tape of steel wound as a coil) and a 
coaxial copper coil, the frequency is 50 Hz. The same happens 
imposing in the Lamination Attributes window the option: Laminated 
parallel to r (stacked steel disks problem).

The only way to run the file on release 3.3 is to impose in the 
Lamination Attributes window the options: Not laminated or laminated 
in-plane.

It would be very helpful to know why the difference in behaviour 
for the two releases (3.2 and 3.3) and if both releases can be used 
to solve such problem.

Thanks in advance for reply

Arnoldo.
