0.33286E-03 is the timestep for my "100 smallest timesteps". idk why it didnt show just now. So, multiply that with 1.05 = 0.349503E-3. So this will be my timestep for my circular tube of termination time 300000ms and d3plot 3000ms? Sorry for asking too many questions i really have no one who can guide me using LS DYNA.

I'm not sure what is going on there to be honest. Try removing the *Implicit General card and see if it still happens. You can also try drastically increasing the DTO to see if you can get it to run. Here's an example:
*CONTROL_IMPLICIT_GENERAL
$ imflag, dt0
$# imflag dt0 imform nsbs igs cnstn form zero_v
1 100.0 2 0 2 0 0 0
