free pre-post processor
Mon, 2007-03-05 10:14 - Karma Yonten
Does anyone know of a good free pre and post processor software for finite element analysis? I'm currently using the academic version of GiD. It's not convenient to create a more complex mesh with GiD, and doesn't give a good integration point stress/strain contours.

a concrete frame modelling in ansys
Hi dear friend,
I'm a beginner in ansys,and in my thesis I have to simulate a concrete frame,so I want to know do you have any ansys example which could help me?
thanks a lot

thanks,
Thanks for this.. I'm also looking for free pre and post processor software for finite element analysis and linked to the websites given above.. It helped a lot, thanks!

SALOME is a free software
SALOME is a free software that provides a generic platform for Pre and Post-Processing for numerical simulation. It is based on an open and flexible architecture made of reusable components available as free software.
It is open-source (LGPL), and you can download both the sourcecode and the executables from this site.

FEM
Can any body tell me the best FEM software for mechanical structures. some tell me abaqus while others favor lusas. i need your advice.
"best" FEM software may depend on many things
Ahmed,
You may have to be more specific in terms of what determines "best" for you, besides the application to a relatively broad class of problems (mechanical structures). Is it reliability? Robustness? Is cost a factor?
ABAQUS is without doubt an excellent code for the analysis of a wide variety of problems in solid mechanics. I'm not familiar with lusas at all so I can't speak to it.
Thanks alot for your
Thanks alot for your information. I am working on solid mechanics, Relialibility and cost are part of my analysis. is there a free downloadable FEM software? I checked ABAQUS v6.6 and couldn't install. license server is required!
thank you.
There are many OPEN SOURCE
There are many OPEN SOURCE FINITE ELEMENT FEM Softwares.
For Solid Mechanics it depend on which aspect of solid mechanics you use. for example CRACK analysis have it's program, ATOMISTIC-CONTINUUM analysis have its softwares and THERMAL analysis have another. Some of them ARE GENERAL
CalculiX
ABAQUS is very powerful and very popular amongst researchers. However, it is quite expensive. As an alternative, CALCULIX is a free FEM software implementing many of the capabilities one can find in ABAQUS. For details see:
http://www.dhondt.de/ and http://www.calculix.de/
I have been using LUSAS for
I have been using LUSAS for 2 years. It is very easy to learn and use. It has also included main nonlinear material models as Drucker-Prager, Mohr-Coulomb, Tresca, Cracking Concrete etc. I have no idea about ABAQUES.
LUSAS vs. ABAQUS
ABAQUS is more popular than lusaas. then i advise you to use abaqus because
there are more informations about it in wolrd wide web but in some civil
engineering applications lusas is better
help: who can give some codes for generating Voronoi diagram
I am studying the FEM, but the polygons elements generation becoming the hard problem. Can anybody give me some codes for generating the Voronoi elements.
A MATLAB function: voronoin( )
The function voronoin( ) in MATLAB may be beneficial to you. Try it. And good luck!
Have you looked at Qhull
Have you looked at Qhull yet? It is used by Matlab and Octave (open source Matlab clone) for their computational geometry functions including voronoin. It is open source.
http://www.qhull.org
generating Voronoi diagrams
a very good code for generating delaunay triangulations and voronoi diagrams is Triangle by J. R. Shewchuk
http://www.cs.cmu.edu/~quake/triangle.html
a more comprehensive package for all needs in computational geometry is CGAL:

Abaqus batch
I would like to know if it is possible to import an iges file using the abaqus batch interface.
If it is possible, can someone post the command lines needed?
Thank you in advance,
Claudio
Re: ABAQUS batch
Yes it is possible. See the script below. Save it to a file , let's say 'igsin.py' and run it with
C:\temp>abaqus cae script=igsin.py
#import igs script
from abaqus import *
from abaqusConstants import *
import part
import sys
#change the next lines as necessary
#path to the igs file
igsFile="C:\\temp\\mypart.igs"
#name of the model where the imported part will be added
modelName="Model-1"
#name of the imported part
partName="myImportedPartName"
if modelName in mdb.models.keys():
myModel=mdb.models[modelName]
else:
myModel=mdb.Model(name=modelName)
#the next two lines open and convert the igs file
#check the documentation for additional parameters to tune up the convertion
acis_file=session.openIges(igsFile)
myPart=myModel.PartFromGeometryFile(name=partName,\
geometryFile=acis_file,\
dimensionality=THREE_D,\
type=DEFORMABLE_BODY)
print "Part %s....imported! :-)"%myPart.name

OpenXFEM++ crack growth open source
Hi,
http://people.civil.gla.ac.uk/~bordas
you will find a link there to OpenXFEM++. We also have other similar libraries. It's not FEM, it's extended FEM, but the idea should be similar. You want 3D?

hi Dr.Bordas
i am unable to download the XFEM++ from the given link, but i am able to see the code used in the extended software . well here von mises stress yield is used for calculation of yield , can u tell me how i can use the tresca yield function for it..
thanks

Openxfem++ Tresca --
Hi again,
If you are able to implement Tresca, then, you can put it into OpenXFEM++, it is straightforward and completely separate from the rest of the code. Thanks, and good luck, Stephane
PS: Please email me, to get the code, there must be a problem on the web site, I have no time to fix it now.

pre/post-processing software for boundary element
hi everybody,
Can anyone explain me how to use a pre/post-processing softoware.
for exemple if i have a FEm Consol Program and i want to see the response of a structure to thermal or mechanical sollicitations.
thank you for answering
RE: pre/post-processing software for boundary element
Generally speaking, a pre/post-processing software should have a template file which can be customized (typically, using a script language) so you tell the software what you want to be printed out in a data file, say for example, node connectivities, material properties, load and constraint data, and in general, all the information that is required by your executable or console program. The next step is to set up the pre-processing information using the pre/post-processing program. For this, you create the geometry, create the mesh, define material, apply loads and constraints, etc. Once this stage is done, you should be able to create the data file directly from the pre/post-processing software according to what you defined in the template file. At this stage, your executable or console program should read that data file to start the calculations. Your executable should also give you an output file containing relevant results to do the post-processing. Typically, the output file will contain, for example, nodal displacement and/or stresses at gauss points. This output file must be readable by the pre/post-processing software so you can visualize your results. At least, that is what GiD does. The following link might be useful for you:
http://gid.cimne.upc.es/support_team/su05.html
and look at "ProblemType tutorial".

I want to modeling stone with ANSYS
Dear friends;I m modeling a historical arch bridge with ANSYS. I modeled stones with SOLID65. Is it true. Could you give meknowledge about this subject,I will be happy. See you later.
Hey You can use
Hey
You can use CASTEM for pre processing. It is a free downloadable software. You can download it from the link: http://www-cast3m.cea.fr/cast3m/index.jsp. It is absolutely free downloadable.
But let me tell you it is software in french language and developed by French Atomic Energy. You can get help in English too using a command opti lang anglias. This I found easy for meshing thing. A better Documentation is available too........ And it is based Object Oriented Language called Gibiane. If interested have a try.......
Inspiration and genius--one and the same.

crash for abaqus
hello
Linux?
I was interested in this software: http://www.freebyte.com/cad/
But it only works on Windows and I am running Linux. Can anyone recommend a similar option for Linux?

I m looking to your help please, my problem is how I
realize a parametric study via abaqus which touch the material young

script evaluate actual young modulus via a function of actual displacement Repeat
until:: Young

Windows8 v.s Linux
Hi all,
Is Windows8 developed with Linux ?
I have found the application Power Shell accepting Linux Commands as: ls,pwd,whoami,.. But this Release of Windows is Vulnerable to Viruses and Bugs. I found it better than Win7 in the beginning but it has lost its steering.
