[Getdp] help on tutorial

[Faisal Ahmed]

Hello Everybody

i am quite new in the field of computational electromagnetics & as well in
getdp. i was trying to do simulation with one of the tutorials files named
as 'Mag_av_2D.pro', for which the geometry is defined in file Core.geo.
I suppose everybody knows which tutorial I'm talking about. I converted
the Core.geo file to .msh format in GMSH. When I try to run the simulation
with
getdp CoreMassive -msh Core.msh -solve MagDyn_av_2D

I get error message as below:

Loading   : Problem definition 'CoreMassive.pro'

It will be very nice to have some opininion for the solution of this
problem. I hope I am not bothering everybody with a very small problem.
