Hi,


I am trying to restart the simulation using initial set of data (100 iterations).
So i have set up the .cfg file as follows,

% Output file restart flow
RESTART_FILENAME= flow100.dat


% Output file flow (w/o extension) variables
VOLUME_FILENAME= flow100

And it got simulated without an issue (“Initial data set” picture).


Then I have set,

% Restart solution (NO, YES)
RESTART_SOL= YES


SOLUTION_FILENAME= flow100.dat

But simulation still runs from the 1 to 99 not starting from 99th iteration (“Secondary data set” picture). (Used mpirun -n 12 SU2_CFD naca0012.cfg code to run the simulation).


Any guide is appreciated,

When restarting, the iterations start at 0 again. We do not keep track of the number of iterations of previous runs.

Hi,



Appreciate for the clarification


So, I assume same concept apply for the convergence history file as well? Cause when I check that file, it has only recorded from 0 to 99 iteration too.


Is there a way to confirm that simulation is definitely continuing from the previous data file?


Thank you again,

For simulation 2, the residuals at iteration 0 should correspond to the final residuals of simulation 1.
If you concatenate the old and the new residual file, it should show a continuous line for the residual values, preferably decreasing.

Hi,


I haven’t tried setting up the residuals/plots yet so I missed that point. Thanks for suggesting me that, it is actually a good tactic.


Can I make residuals recorded in the convergence history file or do I have to generate it in a different file?


Thank you for your help,
