Floating Point Exception Error
 

I am simulating nozzle inside tank. After meshing the domain in ANSYS Mechanical Workbench and Importing in Fluent, I am constantly getting the following message "floating point exception" in calculation.

Please can somebody solve my problem?

I am attaching some mesh images below:

Mostly these kinds of errors occur if you have given any unphysical condition in your problem. or if there is problem in boundary conditions.
