I am running the recent AEM3D preprocessor to generate model bathymetry but I am getting the following error written to PREPROCESSOR OUT FILE. No error is shown in debug_pre file

Answer 1

That was caused by a grid value that is less than 1 in the bathymetry data. I still do not know why but the application worked when I changed the value to 1.
