[CIG-SEISMO] Questions Specfem3d

[Dimitri Komatitsch]

Hi Sebastian,

If you used TRELIS, then in TRELIS you can display the min and max of X 
Y and Z of your mesh (if you did not define it yourself, it means you 
used a default example and then Trelis defined min and max values for 
you, which you can output).

The UTM map projection is done later, from inside the SPECFEM3D code; 
thus if you want to use it, you need to create the initial mesh in 
lat/long, not in X Y Z.

Best regards,
Dimitri.
