Hi, based on the pictures that you shared, I think you need 1 "step" and multiple "substeps". You are using a minimum and maximum time step of 1 s. So if the solver needs a smaller time step to converge, it can't use a time step of say 0.1s or 0.001 s. Try the following:

Number of Steps: 1

Auto Time Stepping: On

Define By: Time

Mininum Time Step: 0.001s

Maximum Time Step 0.1 s

If it still doesn't converge play around with these values (try reducing the minimum time step) and see if that helps.
