I am importing a notepad .txt file that contains the temperature values with respect to position, i.e. T(x,y,z) in 3D geometry.

I am using:

1- Global Definitions --- Interpolation --- import file

2- Structural module ---- Thermal expansion--- int1(x,y,z) as Temperature load ---- Reference Temperature= 0

However, after solving the Time-Dependent problem, when I plot the Temperature in "Results" it shows only the first entry/value of temperature of the imported file, i.e. no gradient at all or not matching with interpolated values plot. When I plot the interpolation it shows the right plotting of T(x,y,z).

Can someone tell me why it is not being imposed as gradient? I am not getting the expected stresses; the result of stress value is much lower than expected.
