ichthyop[severe] null | java.lang.NullPointerException

Hello.
I am a total beginner with ICHTHYOP, I have already read the guide and some topics in this forum.

I work with local stored data (netcdf files).

For the moment, when I want to preview my simulation, I have the following error:
ichthyop[info] {Dataset} Open /gpfs/home/UDCPP/barrier_c/Test_ICHTHYOP/data/nest_1_20150100000000.nc
ichthyop[severe] null | java.lang.NullPointerException
ichthyop[severe] [Simulation] Initialisation failed (performing: SETUP)

Where can this error come from?

Thank you in advance for your help,

Celine

Ichthyop version: 
Ichthyop 3.3alpha
Hydrodynamic dataset: 
MARS3D
Java version: 
Java SE 8
Operating system: 
Linux Mint

Hello,

Did you manage to run the basic examples in the tutorial (in the download section)?

Cheers,

Christophe

Hi Celine.

This error is likely due to a variable that is not found in the NetCDF file. Have you properly defined the names of the dimensions and variables?
