Does anyone know if it is possible to run ANSYS as a solver through MATLAB ? I want to run optimization in MATLAB and change some variables whether they are geometry or material variables and run ANSYS through MATLAB to solve especially ANSYS CFX or Workbench where I can have multiphysics.
If this is possible, I would appreciate it if you can share the method of how to do so.
Thank you all
i have modelled a 3D RC beam and strengthened it with FRP and used cohesive elment for modelling the adhesive .
so for finding theinterfacial strain between concrete and FRP ,which strain must I opt for namely , E, NE, LE, PE
And i want to know what theses stand for(E11, NE11, LE22) . I hav read it in manual but can I get more information on this
I just started to use the Abaqus FE program and I would like to ask some help. I would like to determine the elastic properties of a composite material therefore I designed an representative element but I need to constraint the nodes of each surface to achieve uniform deformation at each nodes on the surface. I tried the multiple point constraints but I alvalys got an error message saying that:
80 nodes are missing degree of freedoms. The MPC/Equation/kinematic coupling constraints can not be formed. The nodes have been identified in node set ErrNodeMissingDofConstrDef.
I am not even sure whethe I am using the correct command to constraint the nodes.
I want to know that is there a novel way of defining several two dimensional contact pairs in Abaqus/Explicit. I know that abaqus has the capability of defining a general contact but it is restricted only to Abaqus standard and 3D Abaqus explicit problems.
I have a 2D plane strain problem where I have to specify more than 1000 contact pairs in the assembly between similar instances of the same part. Is there a fortran subroutine that could be used to determine so many contact pairs?
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 ?

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 .
