Automatic timestepping can not be calculated: “Timestep Calculation Type”

Error

Automatic timestepping lead to a timestep below the minimum threshold.

What happened?

The solution didn’t converge at some time step and the automatic timestepping which was than called failed.

What could be the possible reason?

This error may occur if an automatic Timestep Calculation Type has been choosen and not enough information from previous successful time steps or iterations are available to extrapolate the correct time increment value.

What can I do now?

To resolve this error, please switch the Timestep Calculation Type to either Manual or Mixed under Simulation Control.
