    Hi,

    Time step is directly proportional to elemental length. So, if the length of an element is very low the time step will also drop. From the .out file user has to check the time step and what is contributing for it. When the time step is low computation time will increase drastically which finally can result in run termination with error TIME STEP LESS OR EQUAL ZERO.
