Hi everyone,

I would like to use the function object systemcall to be able to update the 6DoF motion of my body.

I need to use the current timestep value in the bash command I call, and I cannot figure out how to do that.

The best workaround I found so far is to read the log or force text file and write a bash variable with the timestep value.... Which is really silly I think.

Thanks !!

I'd guess that the easiest would be to recompile your solver (okay) or recompile a modified version of system-call (better) that also exports the information you need via environment variables before the system-call is actually called. Maybe something like FOAM_TIMESTEP, or FOAM_ITERATION would be a good name.
