Hi,
I am not a developer, but I ran into the same problem a couple months ago where I was trying to use a very smoothed version of ETOPO1 and was getting invalid Jacobians. I eventually concluded that there is an anomalous value in the ETOPO1 file somewhere, that, despite smoothing, is creating this numerical instability. If you have the capability to visualize the topography file, you might be able to verify if that is true for you, and manually reassign those values.
Best of luck, and I hope this helps.
Hello Specfem developers, I got some errors when I was doing the global calculation with parameters like these:
But when I set TOPOGRAPHY as .false., the mesh generation is working properly. I have tried using highly smooth ETOPO1 data (SIZE_FILTER_ONE_SIDE=50 at run_create_topo_bathy_file.py), but it also doesn't work. What should I do to avoid this problem?
