Hi,

I'm new to Delft3D and am running the Wave module and getting a stack overflow error:

It appears the model runs through the wave computations okay, but crashes when it's trying to do the output:

 use of rescaling in 100.00 % of wet points with maximum in spectral space =  247
 accuracy OK in  99.86 % of wet grid points ( 98.00 % required)

My domain is pretty large with:

 Gridresolution       : MXC             465 MYC           1126
                      : MCGRD        407901

I watched the system memory usage as it runs and it's < 15%.  CPU usage is 100% during the iterations, but it drops down to ~5% when it crashes processing the output request.

I derefined the grid to:

 Gridresolution       : MXC             233 MYC            563
                      : MCGRD        102115

and it runs fine.

Any help would be greatly appreciated.
