Hi, everyone

I just start my research on bounding surface model for soil mechanics. Does someone have documents about programming of bounding surface model for stress-strain behaviour with a piece of program? Thanks a lot for your help.

please suggest research areas( for PhD) in computational fracture mechanics areas. CAE FEA area

Abaqus User Element Python Script

Hi, 

I must use user subrutine UEL in a Python script.

 

elemType1 = mesh.ElemType(elemCode=???, elemLibrary=???)

p.setElementType(regions=r, elemTypes=(elemType1, ))

 

 

what are the elemCode and elemLibrary that i must use????

 Thanks for help 

 

 

 

 

Parallel Computing in the Multi-Body System to Vehicle Dynamics?

Submitted by Xianfeng Ye on

Has someone worked on the parallel computing in the multibody system to the vehicle dynamics? It's what I am doing now. I am faced to make a choice, OpenMP or MPI? OpenMP is a little  easy to program, but with less portability. I prefer MPI and I think if it is a best choice to parallelize the constraint libraries, although it is a bit difficult to program. Am I right? Is anyone  also doing it now? Opinions and suggestions are welcome!

I am a mechanical engineer in Turkey in senior year. As a graduation project I have to model soft tissue cutting operation by using ANSYS. The main aim in the project is;

1.Choosing
the correct material properties (SOLID,SHELL etc.) and correct
method( Prony Series or Generalized Maxwell for
viscoelastic)

2.Creating a cylindirical model as an example
and than creating the orginial model as a representation of the soft
tissue(in this case the tissue must be some living organ ex:liver )

3.By
using the contact modeling (I learned that it requires to have some
detailed experience in writing subroutine) dividing the material into

Is there any computing module which can compute a heap of disk elements in DEM(discrete element method)?

Is there any computing module which can compute a heap of disk elements in DEM(discrete element method)?it'd be better if it is written in matlab or C/C++. I'm doing research on the combined DEM-FEM. I need such module so as to save my time.

Thank you
