Scope: Aria Material
Summary: Value from a NASA14 polynomial function
Description: $\begin{split} T_i &= T + T_\text{offset} \\ c_p &= \begin{cases} &R(L_0 + L_1 T_i + L_2 T_i^2 + L_3 T_i^3 + L_4 T_i^4), T_i <= T_\text{mid} \\ &R(H_0 + H_1 T_i + H_2 T_i^2 + H_3 T_i^3 + H_4 T_i^4), T_i > T_\text{mid} \text{ and } T <= T_\text{max} \\ &R(H_0 + H_1 T_\text{max} + H_2 T_\text{max}^2 + H_3 T_\text{max}^3 + H_4 T_\text{max}^4), T_i > T_\text{max} \end{cases} \end{split}$

An enthalpy evaluator is automatically provided, the reference state enthalpy, and entropy can be adjusted with the h0 and s0 parameters which are added to the appropriate NASA polynomial coefficients.
