question: In a particular 3D unsteady problem let us say I obtain solution for some first 20 time steps by using very low under relax parameters. Now that the flow is developed, I want to start again at t=0 and use good values (default) for under relax parameters. How do I use the solution obtained previously to initialize my new problem?

Re: initialization
You can export the solution using the File->Write->Profile command from the first grid, initialize your solution and reading profiles again.

Maybe there is a better way, but I don't know it.

Hi :)

Re: initialization
does profile files contain all the data at nodes ? i was thinking the dat file does that
