Hi Chris,
My simulation fails for this error:
***** FATAL ERROR **** FATAL ERROR **** FATAL ERROR *****
09:20:53 ERROR: A subdirectory or file unffiles already exists.
09:20:53  INFO:  * in module     aem3d_free_surface.f90                          
09:20:53  INFO:  * in subroutine get_eta_mask                                    
09:20:53  INFO:  * No surface area found
09:20:53  INFO:  * Simulation may have completely dried out
 What can be the reason?
Thank you for your help.
Cheers,
Irene
