As we know the gradient of mean temperature is fixed. I tried fixedGradient and applied the fixed gradient to all profiles but it does not work, specially for high prandtls. I also tried fixedMeanValue but it does not work too!! Is there a BC in openFoam to implement fixed mean temperature or fixed gradient mean temperature? Thanks
