Starting a model from separate flow and transport restart files

[Orlando Silva Rojas]

Hi everyone,

I have run a steady-state flow simulation and a steady-state pure diffusion simulation, generating two separate restart files with obviously different data structures.

I was wondering if there is a straightforward way in PFLOTRAN to read these 2 files in the input deck to start a simulation of flow and transport. I have checked the manuals but did not find anything on this. I would also be happy with tricks allowing me to combine both restart files without the need of pre-processing. For instance, running very short simulations (e.g., 1 second) starting from the flow restart file to first include the flow field in the data structure for a flow and transport simulation.

I will acknowledge any comments or practical ideas.

Best wishes

Orlando

Orlando,

Are you using the same grid?
