- Reduce the maximum time step to see if a smaller time step helps the simulation converge.
- Increase the consistency tolerance in the solver configuration block.
- Consider adjusting component parameters such as ‘Open resistance’ or ‘Closed Conductance’ that make the model more realistic and less ideal.
- Refine the model Review the model for errors, inconsistencies, or incorrect assumptions. Simplify the model by removing unnecessary components or subsystems.
In a simcape model the error is shown as initial condition failed to converge, nonlinear solver advance time one step failed to converge, residual norm too large.e

Hi Gupteswar,
I understand that you are looking to debug the following error in your Simulink model:
Nonlinear solver to advance one timestep failed to converge, residual norm too large.
Kindly provide the complete model & files associated with this error. This error is often encountered when a model is too ideal and exhibits sudden transitions, hence, the solver fails to converge. In such cases, the solver performs transient initialization.
I recommend the following changes to help resolve the error:
Kindly refer the following documentations to learn more about troubleshooting simulation errors & transient initialization:
Hope this helps.
