So with help from someone from CFDOnline, I was able to solve this problem


1. Yes, i switched to using Complied method to get my code loaded into AnSYS fluent accurately.

2. Resolved the 'nmake error' by loading ANSYS fluent from VS Studio v19 terminal prompt

3.  replaced the enthalpy formula h = Cp(t - Tref) with the integral of the Cp over the interval T to Tref. ( This was the major change which resulted in the temperature spots to vanish).
