I want to model post-tensioning tendons embedded with concrete structure. Both ends of tendons are anchored. Can anyone inform me what kind of element most suitable to model the tendons and concrete structure in ABAQUS? I tried solid part for both items, yet as the tendon diameter is very small if compared to the concrete dimension, the resulting number of mesh on the concrete structure is very large.
For those of you looking for FSI simulation on Abaqus platform, recently Simulia has announced the new features in release 6.10, which introduces the capability for performing Computational Fluid Dynamics (CFD) simulation.
So it enables users to perform coupled physics simulations with
Abaqus/Standard and Abaqus/Explicit, such as fluid-structure
interaction between human tissue, a medical device, and fluid flow, more information:
I'm embarking on a project to build a modified copy of a DIY 3D printer. See http://reprap.org/wiki/WebHome to get a rough idea. In my case, I have my own lathe and milling machine, so I can fabricate more substantial components, e.g., by machining aluminum. I also have larger stepper motors, some 3/8" precision rod and linear bearings that I can use.
How can we perform first structural and then thermal analysis in ANSYS (version 12) ? All the examples show the sequence the other way. I can't go for Direct coupled method as the materials are elastic-plastic (plasticity is not supported by direct coupling elements).
I'm using Matlab and mupad in my research .I have managed to plot a few curves using mupad, a powerful symbol computation soft. Since it is theory solution, I want to add the experimental curves to compare the goodness.But i don't how to make the two softwares work cooperated.
I'm mechanical engineer and working as FEA Engineer in GATES. I have
been using ANSYS for 5 years and I want to ask a question about new
version of ANSYS.
I use ANSYS Mechanical 12.1. I connect "geometry" and "setup" to
Mechanical APDL box in "project schematic". Then when I open Mec. APDL, I
can see the cad model (areas, lines, volumes) and FEM (nodes, elements)
but they aren't connected to each other. is there any way to connect
solid model to finite element model?
I am a PhD student at the first months. I have to choose a finite element software to study impact effect on biological soft tissues. After some web researches the softwares which seem to be more suitable are ABAQUS, Comsol Multiphisics and Ansys.
My intention is to develop an user defined material model considering the material as anisotropic porous-visco-elastic.
I would appreciate some suggestions/opinion. I am specially interested in dynamical simulations.
I am using an optimisation algorithm in matlab.I need to start abaqus from Matlab ( Using abaqus job=jobname), later i want to run a python code to extract some history outputs and feed into matlab. The process involves many iterations . Can anybody tell me how i can run the python script from Matlab ?.
I have written the program in C++ which is based on one of BEM (Method
of fictitious loadings) . I know there are a lot of open libraries of
functions for programming for example openCV or OpenFEM. I could not
find Open Source library for BEM. Please if you know them, give links.

I want to know if there are some opensource softwares to transfer the x-ray raw data to representative discrete pole figure data by Euler angles ? Now I know how to calculate ODF from x-ray raw data with the help of "Mtex". But I dont know how to get representative discrete pole figure data by Euler angles, which is used for CP numerical simulation, from ODF.
Hi I hope some users are working on the open source FEM code TAHOE. The link from sandia National Laboratories (http://tahoe.ca.sandia.gov/) to download the software is not working. I got the tahoe 1.2 .tgz from sourceforge.net. But I am unable to create the executable in linux as it is displaying some error. If any one has compiled executable I kindly request you to post it.
A problem we are trying to solve in ABAQUS-6.9 involves user defined Fortran subroutine to be compiled by ABAQUS. The default compiler used by ABAQUS is ifort, but what we have is pgf90. Is it possible to make ABAQUS use pgf90 compiler instead of the default ifort ? How?
