Set gradient of temperature from outside
 

Hi

I have a problem to set gradient of temperature to a value for boundary cells. I need to take gradient values from another file or read from file and assign them as new gradient of temperature. I only find fixedValue or fixedGradient in the forum. My values are changing every iteration but i could not find a way to assign them into gradient of temperature.

Hi,

Did you look at uniformFixedGradient? It can read gradient value from external CSV file. Though it will be single gradient value for the whole patch.
