Hi,

I know that I can get temperature gradient by doing the following: "/solve/set/expert/ "in the console window. and I answered "yes" to keep memory from being freed. however, as i saved cas and dat file for future use, the next time I open dat file, all information regarding on tempeture gradient( dt/dx, dt/dy) disappeared. Does anyone know why I cannot save infor of tempeature gradient in Fluent? Many thanks in advance, please help me. It really takes sooooo long to iterate and I dont want to loss data of tempeature gradient.
