I get the following message while running my Simulink model:

The values returned by mdlMassMatrix, mdlDerivatives, and mdlForcingFunction do not satisfy the consistency requirements at time 1.7646610590354366. The residual value (8.870477525311659E-12) is greater than the requested tolerance (8.8317608663278478E-12). Consider tightening the error tolerances, and/or providing more accurate initial conditions. If the problem persists, check the model for discontinuities in the solution
