      The numerical solution method of TOKAMAK plasma evolution and MHD-equi1ibrium problems is developed with plasma pressure and stability reserve factor given. The numerical algorithm is based upon inversion of variables with use of orthogonal flow coordinates. Comparison is made between numerical and accurate solutions illustrating the effectiveness of the method. Examples of calculating plasma equilibrium evolution with pressure raising are given, the border being free and fixed.
