I think my problem is overclosured nodes that I have. In the first picture here end of my first step, I have some over closured nodes. These overclosured nodes start moving freely when hit my hammer in my last step. After that, one of the nodes hits these elements and my simulation crashes...

Sorry that I could not reply before. Please see my attached file. I use VUMAT for this simulation to run. I was wondering if the contact in STEP-1 is very stiff and it makes the simulation unstable. Would that be possible to have this kind of error in the beginning of the next step ? Here is...

I was able to fix my displacement jump issue. I realized that amplitudes were not continuous when Abaqus goes to the next step. However, I am still getting errors due to overclosure in my last step. This is because I am not having an acceptable element condition on V-Notch impacted surfaces...

Yes, I applied smooth amplitude.

I checked that. It says you should be using an equal amount of CPUs for both models. It actually works on my personal computer. However, it does not generate any abaqus or error files in the cluster. I got in touch with the university staff about this issue. If anything comes up, I will post it...

I attached the .msg file link below. Again, in the first step I applied the V notch impactor (4mm displacement applied). I have not gotten any errors in that step. When I moved to the second step, I got some jump warnings that were the same length as the displacement applied in the first step...

Yes, it is Abaqus Explicit. I have been using the same number of CPUs for both the main model and the restart model.

I use a university cluster for my simulations. I would like to use the restart option to not repeat the initial steps in my simulation. However, the .res file does not recognize my restart simulations. If I use a single CPU, it works. But if I increase the CPU number, the restart option does not...

Hi, I would like to create a V-notch on my DWTT specimen (Step-1) and break it using rollers and an impactor (Step-2). Everything works well for Step-1. However, at beginning of Step-2, I have a displacement jumps warning and I get an unresolved initial node-analytical rigid surface...
