Default Floating point exception error after extending geometry

Hi all,

I'm currently trying to simulate physical experiments to validate my model for later use. The simulation is of a wave tank with a (partial) OWC device in it. In the model, I used fifth order waves with a wave height of 5 cm. The mesh at the water surface is refined to 4 mm in Z and 16 mm in X direction. I initially ran the model with a length of 15 m, to see whether it would run. It did, and so I extended it to a lenght of 35 m, the length of the actual wave tank. None of the input changed, put now I get a floating point exception error whenever I run the simulation. I already tried different mesh configurations but nothing would work.

The simulation is in 2D, (one cell width of 2mm). Inlet and top are velocity inlets and the walls and bottom are no-slip walls to simulate the wave tank.

Can someone help be with this?

Thank you in advance.

Regards,
Bart
