example case for WRF+NEMO+OASIS

Up to Specific issues in real coupled models

Posted by Anonymous at June 13 2025

Hi,

I have been trying for some time now to do a global run for WRF coupled with NEMO via OASIS. I keep having issues (seg fault mostly); and I am unsure if it's due to my settings (namelist and other inputs) or to my executables. 
Is it possible for someone to share with me a couplete set of input files corresponding to a working WRF+NEMO case (global or regional)? That would be of great help.

Best

"Segmentation fault" is usually due to the program trying access an index outside of the range of the array, for example trying to access i=101 in an array A(1:100). 

A good first step is to compile all model components with -fbounds-check (for GNU) or -check-bounds (for Intel). This will slow down the model but it will write exactly what index its trying to access from which array so you can spot the problem. 

Good luck!
