23.2. TIPS for errors at runtime#
23.2.1. Tips in case of BLOW UP or ERROR#
Check your time steps
Eventually increase NDTFAST and/or decrease the baroclinic time step
Check the location of your boundaries (in particular if your blow up point is located close to them): it should not be placed on a too strong topographic gradient, or coastline particular shape (it is usually better to have a boundary normally crossing the coastline)
Check the thickness and value of the sponge
23.2.2. Others possible errors#
If at runtime you got an error in reading bathymetry variable H (code -57)
- ::
you may ask for too many cpus in MPI compared to the size of your grid
XIOS
Warning
The output time step in XIOS must be a multiple of the 3D time step in croco
