I am working on Battery Pack Thermal Analysis for an Electric Vehicle. Whenever I get to the point of pressing "Run Calculation", the solver displays 1 iteration only then displays some info and "Floating Point Exception". Here are the messages displayed in the console:

I am new to Ansys Fluent, so I will be glad if anyone helps me throughout this problem. Thanks in advance!
well, you have two user defined scalar, they uses a transport equation with transient, advection, disusion, and sources.
All UDS are solved AFTER the principal linear system (P-velocity, turbulence, energy, and so on...) You need be carefull with Courant number for advcetive transport of these scalars (a hypernbolic behavior). Co
