Hello WW3 team,

I am currently running WW3 to obatin the WRT source term given a custom input spectrum on a single grid point case.

I have created a bash code to run through “run_cmake_test” and am running the case by case (each spectrum corresponding to a single WRT term). However, I have noticed that the grid process in run_cmake_test” takes ~12 seconds for each run, which is significantly longer than running other modules.

When I run it over thousands of times, “ww3_grid.out” (similar settings to ww3_ts1) can take the majority of the time to run, despite the settings remaining the same. I am wondering if there is any way to utilize the same ww3_grid.out without rerunning it or if there is any alternative methods to reduce the computation time.

I have attached my running record for your references:

Thank you very much for your help.
