Multiple Configuration Simulation
I'm trying to do a piston-cylinder simulation with 3 configurations: an initialization, a piston move, and a piston hold. I want to run the calculation for a while to reach a statistical steady state (initialization, but I start it from a previous solution in a similar geometry, not a zero initial field), then move the piston, then hold the piston in place for a while and collect some statistics. The problem I'm having is figuring out how to set it up so that I can do the initialization once, and then do a number of move-hold pairs. I can set the piston move configuration with two different activation conditions, one for when the initialization configuration ends and one for when the piston hold configuration ends but depending on which activation condition occurs, a different initial values file needs to be read and as far as I can tell there is no way to specify different initial values files for the different activation conditions.
I thought about replacing the initialization configuration with a longer hold configuration (i.e. CFX runs the hold configuration with more time steps) but I run into the same problem because I would want to start it from a previous solution the first time and then the next time around start it with the move configuration results.
Any advice would be greatly appreciated.
