You must specify a fixed step solver in order to run simulation with RT-LAB. Open the 'Simulation/Configuration Parameters/Solver' dialog box and modify the solver type parameter.
Solution Ode1 Backward Euler (ode1be) is a new fixed-step solver introduced in MATLAB R2020a. However it is the only fixed-step solver not supported by RT-LAB 2021. To solve the problem, upgrade to RT-LAB 2022.1 or later. |
