The calculation program FemHC for solving steady state and transient nonlinear heat conduction equations by finite element method is introduced. The governing equation and finite element discretization method for solving the heat conduction problem are defined. The basic framework and core classes of FemHC is described. The calculation accuracy of FemHC is verified by typical heat conduction problems. The heat transfer of three-dimensional turbine blades is calculated by FemHC, and the results show that FemHC can be used to calculate the heat conduction problems of complex structures such as actual turbine blades.
