How can fix that error in this simulation?
显示 更早的评论
I am working on this simulation and it gives me this error. What can I do?
An error occurred while running the simulation and the simulation was terminated
Caused by:
- Derivative of state '1' in block 'hwmid/Aerodynamic_Data/total forces/Subsystem/Integrator' at time 0.0 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)

Derivatives not being finite at time zero are typically mistakes in initialization -- in particular, forgetting that input signals that are updated by a feedback model need to be initialized
But it is also not uncommon to have a model that effectively has a division by t (time) and forgetting that at time 0 that means a division by 0.
