'TIME STEP LESS OR EQUAL ZERO' ----------How do I solve this error?

(OP)
Hi everyone, I am getting this error in Radioss Block. My min element type step (tetra) is 10e-6. I am not sure if I can increase this because for doing that I will have to increase my element length which will only leave me with 1 element through the thickness. And it will not give reliable results. Any suggestions please ? My material has high stiffness and low density which causes the c (sound speed) value in the time step eq to be very high. ( time step = min ele length / c).
