I see, there does seem to be some small amount of overlap between the surfaces in frame zero (shown below). The step time is set to 0.3. This was an arbitrary decision on my part, since I need to see some significant amount of detonation but I can't let it run for three days. Does the length...

Sure, The assembly consists of a number of parts with opposing contact constraints. In the dynamic, explicit simulation, the parts are imported from a previous static analysis along with a predefined field. This is done by using python to grab the assembly and import the predefined field from...

Hello all, I am trying to model a dynamic model in Abaqus Explicit. It is an assembly made of multiple parts that begin moving from rest. It starts out fine, but as the parts' velocities begin to increase, the elements develop "waves", or distortion that looks like waves shown below. This...

Yes, I did.

Hello, I am making a model that consists of 3D deformable "beams" (not beam elements) that are held together by strain energy. By the end of the simulation, the goal is to get the final stressed state of the assembly shown below. This is done in multiple steps. First, all beams are fixed in...

I found a solution that was simpler than that. I was able to use a displacement BC on one of the triggers to move it, as one would do in real life.

The simulation if of a so-called "stick bomb", made of popsicle sticks. When one of the end sticks is released by a user, the other sticks fly apart due to the stored energy. Videos of the "cobra weave" configuration exist on the internet if you want a physical demonstration. I am trying to...

Hello, I am making a simulation where I want to remove a part instance in an assembly after several steps. The first three steps are in Abaqus/Standard, and the final step imports the simulation to explicit. I now need to define a new step where one of the part instances is removed to trigger a...

That absolutely worked. Interestingly, the reason the surface contact wasn't working was actually a formatting issue. There can't be any empty space under the surfaces listed under *CONTACT PAIR, but general contact actually makes things easier for what I am trying to do.

Hello, I've been trying to import the results from a standard analysis into a new explicit analysis for the final step. I was having trouble writing the input file for the explicit analysis, and I have narrowed the issue down to one problem. I have reviewed the Abaqus documentation and have...

Hello, I've asked a few questions about this topic on this forum and they have been extremely helpful. I currently have a model where I can import the state from a standard simulation into a new explicit simulation by writing an input file with the *IMPORT command. The resources provided by...

Hello, I was wondering if anyone here has ever used the *IMPORT command in an input file to create a job that runs a dynamic-explicit step in a new model from the final state in a standard model. I have not created a job using an input file before, so I may be making some basic mistakes...

Hello, I'm a bit new to Abaqus FEA, so please bear with me. I'm wondering if anyone has experience switching from an implicit model to an explicit model in the same simulation. I'm working on a research project that requires several static, general steps and then a final dynamic step. The...
