Hello all,

I have to question about estimating temperature gradient. I have results from simulation on a tetragonal mesh for temperature field. That mean I know all the temperatures at the 9 nodes of a tetragonal cell. Now I would like to calculate the temperature gradient of the cell (I assume whole cell has a uniform temperature gradient). Can anyone help? Thank you so much.

you can use the shape functions in a Finite Element manner
