Hello everyone!
I'm doing CFD propeller marine. But I am errored. Can you help me?

Error: floating point exception
Error Object: #f
Registering ReportDefFiles, ("C:\kp_files\dp0\FFF\Fluent\.\report-file-0.out")
Calculation complete.
floating point exception generally occurs in FLUENT when the solution diverges, it can be caused by multiple factors including but not limited to:
- Poor mesh
- Problematic boundary conditions
- High CFL number
- Pressure-Velocity coupling scheme
- Order of simulation (First Order/ Second Order ... )
Some times it can arrive due to mis-communication between nodes when running solution in parallel, but it is rare
A floating point exception is an error that occurs when you try to do something impossible 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.
