My results show platform/compiler/CPU dependency

Due to some intricate differences between different compilers/platforms some minor differences in results are expected. Bit-by-bit match of results using different numbers of CPUs is impossible also. But the differences should be small and should stablize over time iteration.

Run crashed with a fort.11 error message "QUICKSEARCH: no intersecting edge...."

First you need to check the results before the crash (e.g. surface velocity) to see if anything is outrageously wrong. If the results look reasonable, this may be related to the version of SELFE you are using; contact the developers for more info.


How to do a tidal simulation with SELFE?

The simplest way is to use SELFE 2D. If you have to use SELFE 3D, make sure the bottom boundary layer is reasonably resolved.

My run crashed; how can I find out why?
