      “Time step too small” appears when current time step is less than 10 % of the initial time step. Error message can be avoided by decreasing the minimum time step to continue the calculations. After loading your problem go to Controls panel and select Time step options. Change the minimum time step to a very small number, or zero. Zero minimum time step means that the minimum time step is calculated automatically by code.
