Hi every one...



I finished my master in mechanical engineearing about eight month ago ... and in my Master career, I wrote a Fortran Finte element code with capabality of  mortar cantact analysis[1,2] and rate independent plasticity with kinematic and isotropic hardening and with large deformation capabilty for isotropic materials[3,4]. My code converges very well and I achieved quadratic convergence and I didn't use any comercial Fe packages like ansys and abaqus .....

I have calculated the J-integral using ABAQUS for 5 contours but I could not find any information about the paths of the J-integral contours. Do you know how we can get the paths of the requested J-integral contours or equivalently how we can define the paths of contours in ABAQUS? 

Hi. I'm working on multiscale modeling of soft tissues. I'm working
on modeling an orthotropic wavy fiber in WB. I write an APDL routine to
change the element coordinate system of each element with accordance to
the fiber curvature. Ansys documentation said that in the case of large
deflection analysis, the element coordinate system will be rotated with
accordance to element rigid body rotation. My problem is that, after the
solution, the elements coordinate system of some elements rotate
more/less than the rigid body rotation of the elements and fiber

It’s with great pleasure that we announce the release of version 2.0 of FEBio (Finite Elements for Biomechanics). This new version can be downloaded here .  FEBio is an open-source finite element package, specifically designed for solving problems in the field of computational biomechanics. This new version includes some major changes and contains a number of new and exciting features. Some of the noteworthy changes and additions are listed below.

Dear Researchers,

I am trying to find out which was the first ABAQUS version, wchich includes the hyperfoam material model. I haven't found any version history about this. Could someone tell me the very first version of ABAQUS in which the hyperfoam model was included?

Thank You!

Is it possible to model and do the thermal analysis of a thermosiphon loop using ABAQUS.

Greetings all,

i want to know, is there any way to measure edge length ( "curves" specifically,  not looking for straight edge length  using distance between vertices as query feature :) ), and also to get vertices co-ordinates in  local co-ordinate system; in ABAQUS CAE or using python scripting.

my problem is somehow related to above query,  can manage solution with 'other' tricks, but want to know any standard methods are avaliable.

Any help is appreciated.

Thanks,

Hello everyone

Recently I've modeled 3 different kinds of natural gas burners in ANSYS Fluent (all of them non-premixed). I've used “Species Transport”, “Standard K-Epsilon” & “Eddy Dissipation”; then I ignited the model with “Adapt>Region, 1000Kelvin”. Streamlines are somehow OK, but maximum temperatures are approximately in all models 400 degrees more than experimental data. I asked some scholars and they told me they have same problem. Can anybody guide me to a model with more accurate result?

 Hi,

I just posted the Matlab source code of our new 3D Fast Iterative Digital Volume Correlation (FIDVC) algorithm to our lab website:
