Dear All,

I want to simulate a cylinder in a numerical wave tank and I've been using OF2.3.0. Previously I got no error when implementing this solver in a two-dimensional problem, but now in this 3D case, I have this following error:


wrong token type - expected Scalar, found on line 0 the word 'nan'M FATAL IO ERROR:
[23] wrong token type - expected Scalar, found on line 0 the word 'nan'
[23]
[23] file: /scratch1/ele12/OpenFOAM/a04f1v3/processor23/system/data.solverPerformance.p_rgh at line 0.
file: /scratch1/ele12/OpenFOAM/a04f1v3/processor23/system/data.solverPerformance.p_rgh at line 0.

In OF2.3.0, the p_rgh boundary condition imposed for a no-slip boundary is fixedFluxPressure, with value uniform 0. But often from a tutorial case of wave2foam, I noticed the p_rgh boundary condition imposed on a wall surface is zeroGradient.

I think both terms have the same physical meaning. If not, could this be one of the reasons causing the above error? My mesh is okay as I did check the mesh.

Could anyone give me a hint or suggestion please?
