NOISE command index 0

When running a sim using the NOISE ON stack command the following error is produced:

Thanks. The noise implementation currently isn't maintained. To be honest, I think it needs to be changed/extended anyway, the current implementation is very simplistic.

True, but I think we can still easily fix it for now until we have a more advanced turbulence model.
