Restart error occurred in the aeroelastic case

gtc · October 4, 2022, 00:00

When I tried to restart simulation of aeroelastic NACA64A010, some error occured with information

Error in "void CSolver::Restart_OldGeometry(CGeometry*, CConfig*)":
-------------------------------------------------------------------------
There is no flow restart file solution_flow_00024.csv
------------------------------ Error Exit -------------------------------

In fact, my settings for restart as follows,

%
RESTART_SOL= YES
RESTART_ITER = 25
%
% Read binary restart files (YES, NO)
READ_BINARY_RESTART= YES
% Restart flow input file
SOLUTION_FILENAME= solution_flow.dat

I was wondering why it calls for **_00024.csv file while admits **_00023.dat file?

The cfg file is similar with the test case provided in the TestCases/aeroelastic and the version of SU2 is 7.3.

I couldn't fully understand the question but you need to check your "RESTART_FILENAME=" output for the correct name. Once you have a restart file after stopping the simulation, you need to change the restart file's name to "solution_flow.dat" as in your cfg file and try to run the simulation again.

You can check the SU2's website for more detailed explanation.

Thank you for replying. But it is not the fault. When restarting the aeroelastic case, it only permits *.csv files to read its old geometry. It seems that SU2 is unable to restart the aeroelastic case at present. Through adapting the source code, I have stored the generalized displacement and velocity, as well as values of plunge and pitch. However, when restarted from those, it still can not recover the original dynamics.
