The DEM is seamlessly used inside the process, thus it is not straitforward to know before launching computation if it is correctly handled.
A gdalinfo of any granule GEO_DATA with stats gives informations if the Z data correspond to DEM value but after the processing (which can be very long)
It would be interesting tohave a small pre check, like that :
Perform direct location on DEM on one band and all the detectois with line sampled at approx 0.5° and at first and last col. For each value use the DEM object to check of a tile is present.
A WARNING could be printed if the DEM do not cover the area
