Hi,

I am currently trying to use Fluent to make a Numerical Wave Tank. I am using Vof method, and open channel waves. I am trying to create a 2D tank. An error is occurring before any iterations of the simulation even complete. - 'Error and Node 0, Floating Point Exception', 

I have tried the normal steps like ensuring mesh sqewness is below 0.95 and orthoganol quality above 0.1. I have tried reducing the time step, dosent seem to work. I am pretty confident that by boundary conditions are correct, but I am still not sure how to solve the error. I have played around with different model as well ant it dosent seem to help.

If someone could help me with this, it would be greatly appreciated.

Check the VOF model settings to ensure they are correctly configured. Please check the VOF model is correctly selected (e.g., Geo-Reconstruct or Compressive).The interface capturing scheme is correctly chosen (e.g., HRIC or Geo-Reconstruct).

I am unsure as to the specicifc VOF settings you have suggested to look at, these are the multiphase settings i have chosen.

Go to Solution - Methods - Spatial discretization

Unfortunately I have tried to run the simulation with all four schemes and two different VOF models, and I am still recieving the same error.

If there is anything else i could do to fix this error, any help would be greatly appreciated.
