Having isues with setOlaFlume exmaple when i change the wave dict to stremfunction wave with 32 terms as given below the model just gives this error..

Can anybody please help me understand what this error is?

Hi everyone,

I'm working on a 3D wave tank simulation using the most recent version of olaFlow with OpenFOAM v2412. I need to implement a relaxation zone (sponge layer) near the outlet to improve wave absorption and reduce reflections.

So far, I’ve successfully set up wave generation using waveDict and applied the activeAbsorption feature at the outlet boundary. However, I would like to add a relaxation zone or sponge layer in the domain itself (not just at the boundary), so that absorption occurs more gradually—similar to what’s done in some reference papers.

I’m not sure how to configure this properly in fvOptions, waveDict, or any other required files. I would greatly appreciate it if someone could guide me through the necessary steps or share a sample case with the relaxation zone setup working in a 3D domain.

Thanks in advance for your help!
