    "Waviness" in elements in Abaqus Explicit

    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...

    Movement Without External Forces

    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...

    Removing an Instance in an Explicit Step

    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...

    Defining Explicit Surface to Surface Contact In an Import Analysis

    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...

    Creating a Surface on a Discrete Rigid Body Using *IMPORT from Standard to Explicit

    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...

    Using *IMPORT to transfer final state from an Abaqus Standard model to an Abaqus Explicit Model

    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...

    Using Results from a Static Implicit Model as the Input to a Dynamic Explicit Model

    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...
