Increasing the sampling rate for noise tomography simiulations

I want to increase the sampling rate by defining a smaller DT parameter in Par_file in noise tomography simulation. However, the DB.X2.MXZ.semd file is not generated in the ad joint (2) step. I receive the following erro in the third step"

cp: cannot stat ‘OUTPUT_FILES/step_2/DB.X2.MXZ.semd’: No such file or directory

time step parameters

NSTEP = 300
DT = 0.12d0

Please post this as a new issue on the corresponding github repository:

all SPECFEM code related issues and discussions have moved to the corresponding github repository sections.

many thanks,
