[Users] SPH in EinsteinToolkit

[Stefan Ruehe]

Hallo, 

first thank you for your advice. I will make a google group until
tomorrow, where we could discuss how to integrate SPH in the ET. 

Roland, to your question, I am not sure which major problem you mean
regarding the MPI process, but I have made test how to couple SPH with a
grid based background and how to take advantages from the grid. 

I am afraid I could not call in into today´s ET phone call. 

Regards, 

Stefan
