A transient heat transfer model for anisotropic material is established based on Element-Free Galerkin (EFG) method. The model can simplify the pretreatment for anisotropic material, which make the thermal conductivity executed by orthotropic factor and off-angle. The proposed numerical model and MATLAB programs are verified by complex engineering heat transfer problems. The effects of orthotropic factors and off-angles on solutions are investigated. The appropriate orthotropic factors along the large size of geometries and appropriate off-angle make the temperature distribution more uniform. The solutions obtained by EFG show a higher calculation precision than the FEM solutions for the transient heat transfer problems in practical problems.
