I am implementing finite difference scheme for the simple 2D Laplace equation. I am facing problem in imposing boundary conditions in 9-point stencil. What boundary conditions should I give at the vertex i.e. at the corner where two boundaries intersect.
e.g.- For square plate what should be boundary condition at four vertices?
What should be the boundary condition at vertices in Dirichlet problem?either homogeneous or non-homogeneous?
I am a new user in ABAQUS. I want to do an analysis on a cantilever beam, where force applied to the beam deforms it, and depending on its deformation thedirection of the force changes.
In order to calculate the change in direction of the force I needDISPLACEMENT INFORMATION at two different set of nodeswhere forces are being applied. I am planning to use UAMP for
I would like to submit a job at a defined time. I know we can do that on the CAE, but I prefere to use command lin, and my current model can't run on CAE. I checked on the help but I don't find how to submit an Abaqus job at a predefined time or to postpone a job of few minutes/hours, from command line.
Abaqus 6.13 - Live Webinar! July 23, 9am EDT and 12 pm EDT.The latest release, Abaqus 6.13 delivers a number of powerful, customer-requested enhancements for modeling, meshing, visualization, contact, mechanics, and performance. These improvements enable customers to reduce development time and costs, while increasing the efficiency of the product development process through highly accurate simulations of real-world product and material behavior.
New web page of Finite Element Analysis software Z-set is now open:http://zset-software.com/ What is Z-set
Z-set is a computational code devoted to the analysis of material and structure behavior, involving a finite element solver and a collection of specific tools for material parameter calibration, preprocessing and postprocessing computations. Z-set is the result of 30 years of close collaboration between the
I am trying to plot the dispersion curbve for wave propagation in an ALuminum beam under S0 and A0 lambwave. My simulation has completed and I thin the results are reasonable as long as visualization is concerned.
I am trying to plot dispersion curve for these two waves using Abaqus outputs. As far as I know I need to use Abaqus outputs such as displacement or velocity for calculation of wave speed.
1- How would I calculate wave speed by Abaqus outputs and is this calculated wave speed the phase velocity or group velocity ?
I have a 3D orphan mesh in abaqus and I need to select a group of nodes that belong to the orphan mesh and that would have been on a 3D surface of the parent solid before it was orphaned.
I know how to do this in Abaqus/CAE, but I don't konw how to realize it using python scripts. If there is a method, just like using "findAt()" to select a surface by coordinates , to select all the nodes on a outer surface of the orphan mesh and to select all orphan elements?
Any tips on selecting exterior nodes on one side of an orphan mesh ??
I've got problems using SPH (smoothed particle hydrodynamic), Is SPH analysis in ABAQUS coupled with heat transfer analysis??? I'm trying to simulate Friction Stir Welding (FSW) with SPH Method, I need to predict temperature history during welding! Is there any software to do this??? THANKS TO ALL
i want to analysis a model in anasys workbench with modal analysis.but i Encountered to problem.Bad mesh generation (as you see in the below figure) happened that i don know how to solve it,could anyone help me ?
I am working on a project using abaqus to simulate miling process. As the first stage, I have to be able to simulate cutting process in Abaqus. I have looked up Abacus 6.11 documentaion a lot but did not find too much of usefull information. Could any one kindly give some hints how to develop such model or introduce me some usefull complete resources?
I am working on the simulation of micromachining of “glass” in abaqus. Although the glass is brittle, it shows some plasticity in micromachining because of the high hydrostatic pressure field present in the machining region. Now I am looking for an appropriate material model for glass with elasto-plastic behavior which allows element deletion. I am not sure if "johnson-Holmquist damage model" is suitable for machining simualtion or not? I would be very thankful if anyone would please help me.
I just started using ABAQUS. I was trying to plot a graph for stress vs strain for a simple problem, plate with a hole. I could use some help here. Really appreciate it if anyone could help me with the steps.
I met a problem in ABAQUS. When I try to solve the same problem with implicit method and explicit method, theoretically, the explcit method requires less memory than implicit method, but for the same mesh density, I can not solve it with explicit method for the not enough physical memory problem, while the implicit method is able to solve it. And for the explicit method, how to edit the memory? How to explain this phenomenon?
I have a problem visualising specified displacements from a modal/buckling analysis.
当解决代数方程组[K]{u}={f} resulting from FEA discretization, the vector {u} does not have components for the specified displacements, zero or not zero, because the corresponding degrees of freedon (dof) have been eliminated. To visualize all the displacements, even the ones that are specified, we recover them from the input data to create a longer vector {u|u*} where {u} are the active dof and {u*} are the specified dof, zero or not zero.

Hello everyone I have a question about Abaqus verification for a Mooney-Rivlin hyperelastic material example which exist in ABAQUS Documentation/Abaqus Verification Manual/2.2.1 Elastic materials/VIII. Hyperelasticity with Mooney-Rivlin strain energy function. In the example for a Test data input-uni axial tension the company Defined a stress-strain curve as input for material property(Nominal stress-Nominal strain). But when I plot these parameters(Stress -nominal strain) as output of the software
