Renormalization group(RG) theory is a very important theory to research phase transition and critical phenomenon. With the development of the computing technology
numerical simulation methods based on the RG are used to compute the physical parameters. The corner transfer matrix renormalization group(CTMRG) method can get high precision results even if the physical system is in the critical status. CTMRG method is used to find the critical point of the twodimensional Ising model. The numerical critical coupling constant is consistent with the exact result with good precision(10
-5
).
