I need some help in running ARPS model

I have some problems in running ARPS. When I finished the
initialization and make it to run

on my PC, it always stops after several time steps. It seems like it
has made some

caculation, that is to say, I think, the model has read through the
input namelist and the data

sets to initiate the model and there is no severe error in it. But why
it stops ?!

I hope someone here could give me some advice, thank you!
