Solving a system of nonlinear differential equations with logical conditions in Wolfram MathematicaDescription

Good day! It is necessary to solve a system of 12 differential equations with an abundance of logical "if" conditions. I solve in Wolfram Mathematica, but the standard NDSolve methods do not work because of these conditions, I implement the Runge-Kutta method manually, but I get unsatisfactory results and a very long solution. I will be glad to cooperate with a mathematician who can help solve my problem.
