Hello, I wanted a know if I can run densit.f with events using cgrid.cgrd instead of newxyz.f

Is it mandatory to use newxyz.f with densit.f ?? Please send in your comments. Thanks in advance.

It's not mandatory at all: densit and newxyz are completely unrelated. You can choose how you move the mesh and how you specify the density independently.

Thanks, What I meant to ask was the difference between densit.f with cgrid.cgrd as opposed to densit.f with newxyz.f. Is it something to do with binary or coded? Can you please clarify. Thanks a lot.

Again, I don't see any connection. One specifies the density, the other the mesh motion. Why do you think they are connected?

Only because they are user coded programs. Thanks for the clarification.
