Hi,
I am trying to run the following deck file. But there is some problem. It shows Zero error still it cant complete run.

Hi Harsh
If you could see your DT is very high. What material you are using? Kindly verify your units.
No nodes/node groups are selected for the imposed displacement load collector. Please update the same and also let us know which unit system you are following in this model?

Hello ,
Nachiket, I tried with lower time step also. i.e 1e-006 but result is same. I use Mat Law 36, Material is Plastic PolyPropelyne.
George, I will Correct the load collector. Unit System is g, mm, ms.
Hello,
I changed time step, add node set to Boundary condition. Still same result.
The problem is with rigid element. just try to give rigid on outer surface and run the simulation.
Further, I would suggest you to follow tonne,mm,ms system.
I think changing time step wont work here because the system calculated time step is much higher, so solver will try to choose maximum of the system calculated and user fed.
The model is having only rigid body and a rigid body element will have very high time step as there is nothing to solve for it. Thus you are getting high time step and job stops.
As this is an impact problem with part located very close to rigid wall, remove the rbody from it and run.
If it is a free fall impact, make use of initial velocity (calculated at height just above the ground)as boundary condition.
Reviewed your model.
In this model you are trying to impact a rigid to rigid, and there is no physics happening in this simulation. RADIOSS takes the rigid body time step to run the simulation which is very high and the run terminates in one cycle.
