HI I am using ODE 15s solver. my model consist hydraulic and mechanical model and simulations shows following error.
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
