22.2. TIPS for errors at runntime

22.2.1. 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

22.2.2. 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
