Quench Simulation with finite difference. Assistance with implementing variying thermal conductivity (k) for changes in temperature (T))

Hi there,

i need help trying to implement the kth_polyvec below for the range of temperature values illustrated below. Thank you in advance. kth_polyVec = [ ? ];

%% pre-processing

% thermophysical properties

rho_polyVec = [7939.8, 0.32912];

kth_polyVec = [ ];

Cp_polyVec = [472.2, 0.25];

Does this work?:

if T >= 1066
    kth_polyVec = [14.6, 0.01];
else
    kth_polyVec = [50.3, -0.02];
end
