Hi,
A floating point exception is an error that occurs with a floating point number, such as divide by zero.
In fluent floating point error can be caused by many factors such as, improper mesh size, defining some property close to zero. However, floating point exception is very specific case that is being solved, the actual reason can be determined by changing one quantity (can be mesh, model, parameters, boundary conditions etc.) at the time.
Can you please try to check mesh?
Thank you.
