Hi,

I have sort of the same problem. Whenever I try to run the galaxy.param
file, with the standard cosmological paramenters

It doesn't go any further. If I change the boxsize to any number, it will
run, but I can visualize the model properly.

Does anyone have a solution to this problem?

Cheers,
Michael
