I am doing thermal stress simulation of a gas turbine stator blade made of TiB2. However, while defining the "Coefficient fo Thermal Property" of the material I am getting an error message saying "Unknown variable Tempref". The expression follows here -
(alpha(T[1/K])[1/K]+(Tempref-293[K])if(abs(T-Tempref)>1e-3,(alpha(T[1/K])[1/K]-alpha(Tempref[1/K])[1/K])/(T-Tempref),d(alpha(T[1/K])[1/K],T)))/(1+alpha(Tempref[1/K])[1/K](Tempref-293[K]))
How can I resolve this problem? I have also attached a picture of the problem. Thank you.
