Hello,
I did a CFD-Simulation on a fine triangular mesh with ~1000 timesteps. I need to Interpolate the Solution for everytimestep onto the new coarse cartesian mesh. Both mesh have the same Geometriy, except for a small wall on the fine mesh. But thats no problem because ansys interpolates data into where the wall was.


The way I do it currently is (for e.g. 10 timesteps): run a simulation on fine mesh --> write Interpolate file at time step 10 --> go to Solution files and read the Solution at timestep 9--> write Interpolate file at timestep 9 --> go to Solution files and read the Solution at timestep 8 --> write Interpolate file at timestep 8 ->.... do that for every time step and after that:


Open fluent with coarse mesh --> Read the Interpolate File at time step 1 --> Export Solution data at timestep 1--> Read the Interpolate File at time step 2 --> Export Solution data at timestep 2 --> repeat until last timestep.


For a Simulation with 1000 timesteps, it would take too long to do it manually. Can I for example write the Interpolate file for everytime while the calculation is running. That would atleast save some time.


Thanks
