I have a 2D lattice structure, where each strut consists of multiple beam elements (B22). The lattice is sandwiched between two plates, that compress the lattice. I run the simulation on Abaqus Explicit and apply General Contact. However, already in the very first computation, before the lattice...
Hi,
I'm trying to do an axisymmetric coupled eletrical-structural analysis in Abaqus 2017, for which I select the "CoupledThermalElectricalStructuralStep". However, there are no "Coupled thermal-electrical-structural elements" available to do the simulation.
For the 3D case, there are a bunch...
Hi everyone,
I'm running an ABAQUS/EXPLICIT simulation where I get a lot of initial edge-edge overclosures.
In both, the GUI and with Python, I can set the settings for these overclosures within the "Contact Initialization" tree (e.g. CInit-1). However, when I create the "General Contact" in...
Hi all,
I'm running explicit simulations of a lattice structure with beam elements that deform significantly (i.e. 80% strain). Most of the time, the simulations run just fine. However, in some instances, I get the following error message before the simulation is finished.
When I track down...
Hi,
When I run my Abaqus/explicit simulation, sometimes it is not converging. The output looks as follows and keeps on going forever, without moving on to the next interval. Is it possible, similarly to the implicit solver, to set a minimum stable element size OR set a maximum number of...
Hello everyone,
I have a 3D lattice structure created meshed with beam elements from coordinates and connections. Is it possible, to create a solid model from it? More specifically, to extrude the beams and mesh them with solid elements (without actually having a solid 3D model/part).
I'm...
Hi everyone,
I'm trying to run an Abaqus Explicit simulation on a cluster via bash. Regardless on how much memory I allocate (I tried up to 60 gb), it's not enough and I get the error message:
The error appears during the preprocessing after the STABLE TIME INCREMENT INFORMATION is created in...
Hello everyone,
I have a structure, where I want to constrain the nodes on one surface in X direction such that they are allowed to move, but only in parallel. Or, in other words, all nodes on the surface must move the same distance, if there's movement going on.
There certainly are some...
When I allocate beam elements in a 3D model, Abaqus asks me to define the cross-section orientation (and normal?). I have a lot of elements, so I'm looking for an efficient way to define the direction. My beam cross-section is circular, so the direction doesn't really matter. Is there a way to...
Hi,
When I create parts, reference points, planes, etc. Abaqus allocates random reference numbers, which are addressed by following commands to e.g. change the properties. For example: a.rootAssembly.datums[10].
Question 1: Is there a way to allocate these numbers manually rather than...
Hi everyone,
Using Python, I'm trying to select the faces of all instances with getByBoundingBox:
faces = a.rootAssembly.instances['Part-1'].faces.getByBoundingBox(...)+ a.rootAssembly.instances['Part-2'].faces.getByBoundingBox(...)+...
Hi,
I'm trying to run my abaqus (python) code multiple times in a loop. I call it through the cmd window abaqus cae noGui=progname.py, which works fine. it executes my program that's in a for-loop for n in variable1: "PROGRAM CODE". At the beginning of my program I load the modules etc. and in...
Hi,
I'm trying to mesh a cylinder in Abaqus 6.14, where (1.) one half should have a finer mesh than the other half and (2.) the outside should have a different mesh than the inside. I created two partitions for that: (1.) I split the part in half and (2.) I create an inner cylinder partition...
Hi everyone,
I'm trying to run Abaqus through a command line with abaqus python d:\file.py. However, I receive the following error message:
Traceback (most recent call last):
File "file.py", line 1, in <module>
from part import *
File "SMAPython\SMAPytLibPy.m\src\site.py", line 120, in...
Hi,
After switching from a working 2D model to 3D, I'm facing the following error message after about 20 iteration steps:
I'm trying to simulate a 3-point bend test using XFEM. The model works and converges fine when I suppress the cracks in the assembly, so it's definitely the XFEM crack...
Hi everyone,
I have a notched part which I pull apart to create a crack. For the crack, I use XFEM and it works well. However, when I try to extract the load-displacement data, I only get a straight line. The crack is clearly initiated and growing, which means that the load should decrease...
