I am doing project in Journal Bearing. I want to run Contact Analysis in ABAQUS to understand the Tribological properties. Could you please help me to learn the Contact Analysis in ABAQUS.
I came across a wonderful site a couple of weeks ago. nb.femhub.com
FEMhub is still at its beginning stage, but it can already do lots of interesting stuff. For someone like me who teaches numerical/computer methods in engineering at a developing country where computing is costly, tools like FEMhub are very much welcome.
More about FEMhub on my website. Try out the example worksheets and I think you'll be pleasantly surprised.
As we all know, finite element matrices are sparse and many memory can be saved if their sparsity is exploited. Due to the latter, we are often provoked to declare the nxn stiffness matrix as a sparse one just before the element loop. Be careful of this method since the larger the matrix the slower the assembly operations. There is a better and more efficient way to code the assembly procedure in Matlab. I will show how to accomplish this.
hello to every body ;)
Iam hasani- gradute student
I'm new user in adina. i worked by ansys and abaqus for several projects.
in adina when i choose control>solution process...>adaptive meshing> full the program return it to none!.
i tried to understand about the reason. but in fact i can not find the problem.
i think in program , there are some constraints that should be change before the full adaptive meshing.
please help to find the problem. thanks
Download your Free Abaqus SE at: http://campus.3ds.com/simulia/freese
SIMULIA Academic programs would like to offer you a complimentary copy of our Abaqus SE (student edition). Now students can have their own personal finite element analysis tool to use on or away from campus. Abaqus Student edition is ideal for students using Abaqus as part of their coursework as well as for practicing engineers who wish to become more proficient with Abaqus.
IOSO optimization technology has been used in turbomachinery for more than 20 years and applied on real-life objects like aircraft and power engines. Let me offer you some more examples.
I need a free autoCAD software to model the complex 3D geometry of human brain. It is desirable that this software should generate output files readable to Abaqus/CAE for mesh generation. I wonder whether these is such a software available. An alternative way is to handle the geometrical modeling myself but I need to know the details of the file format used by Abaqus/CAE. Does anyone have a clue?
Thank you very much!
Dear friends .
This is the first time i am using abaqus for analysis. I am doing a moving load analysis of a bridge .I have planned to apply a distributed load and vary the profile using DLOAD . Do you think its a good idea ?. Can anybody send me an example file of DLOAD.
Thanks and Regards
I've been trying ansys for a few weeks but in vain. I'm trying to inject a heat source(laser) on a 2D rect plate. I'm not sure on the corrct way to add the boundary conditions. This is what I do:
1. assuming room temp so i added 298K to the bottom, left and right using define loads >add_temp>lines
I'm using Ansys 12 for modeling and simulation. can you help me that, how I can enter data loads as boundary conditions for a piezoelectric cantilever beam?
thank you for your assistance.
i am modelling a concrete beam with FRP bonded to beam with the adhesive. i hav tried to simulate adhesive using cohesive element Abaqus(from manual) for the past 2 months, but am getting missing property definition for those elements.I am not sure the procedure I hav followed is correct, so please send me the procedure for modelling cohesive element and the contact between the adherent faces.
waiting for the reply
I will be setting up an open source project for parallel finite element analysis in the next month or two. I am just wondering what the community's opinion is regarding the best repository to use.
SourceForge? Google Software? Others?
Your opinions are welcome.
Can any body tell me hw to solve inverse dynamics problems in adams???
I'm doing final project in the area for Crack Like Flaws based API 579. I'm having trouble with level 3 Assessment Procedure and should using ANSYS to solve problem. Is there anyone who have complete step by step procedure in Crack analysis using ANSYS based API 579 for level 3 ?
Materialise launches new Mimics® version: Mimics 13.1

i'm doing finite element modal analysis of composite structure using ANSYS v11. however i got problem with modeling composite laminates. i hope someone can show an example on how to model the composite laminates. i had looking for the related tutorial but couldn't found one.
Let us introduce you some new application examples of IOSO optimization technology employment in turbomachinery.
First example is the application of IOSO software connected with Concepts NREC software aimed at improving efficiency of 10-stages compressor, you can download it from here
recently i encountered a problem when using abaqus .i wanna define shear distributed load along a surface,
the magnitude of a single point is related with its velocity.but it looks that abaqus does not support this kind
of load even in VDOLAD .how can i do to realize it?
thks a lot .

As a regular remark, we would like to give you a brief explanation of our approach to Design Optimization.
I' m trying to make a model in VUMAT for shape memory alloy based on Lagoudas 's thermomechanical constitutive model. It seems that It's necessary an iteration to evaluate the thermoelastic prediction.
My questions are : is it possible to use an iterative loop in the VUMAT or it's better to avoid it??Could someone suggest me a different way so that I can avoid the iterative loop?
We would like to offer you some third-perty references to IOSO optimization technology from well-known scientists in this area
i have modelled MODEIII case in FRACTURE MECHANICS IN abaqus
PLEASE TELL ME PINNED BOUNDARY CONDITIONS AT WHICH EDGE/FACE WILL BE APPLIED IF I MODEL FULL MODEL FOR OUT OF PLANE SHEAR LOADING,i.e, MODEIIII case
