Hi Shabina,
The error suggests that you have incorrectly modeled the dynamic system, resulting in a singularity.
This is most likely due to the output value being fed back into the system equations. For example, if the system equation includes a term like tan(θ) and the initial output value is θ = π/2, running the simulation at time t = 0.0 will result in tan(π/2) = ∞, producing an infinite value.
Please check the system logic and governing equations.
