Abaqus dynamic explicit

Hi all,


Would you please let me know if it's possible, how to identify the length of mesh, time period of step, factor scaling, ... of an Abaqus dynamic explicit problem.

Thanks in advance,

C/C++/Csharp VS Fortran, Which language is preferable for computational Mechanics?

Dear All,


Please give your valuble comments on the subject: C/C++/Csharp VS Fortran, Which language is preferable for computational Mechanics?

How to study a inverse problem? Know the orbit, solve the constraint condition.

Dear all,

Now I face a noval problem, and I do not know how to deal with it, even cannot begin the first step.

As we know, the formulation of a classical mechanical question  is given the initial condition and the constraint condition, and solve the unknown orbit. Now I face a inverse problem. I know the initial condition and the orbit, and would like to solve the unknown constraint condition.

Is there anyone could give some seggestion, I don't know how to do it. Thanks.


Selection of element bsed on the location in abaqus using python script.

I'm facing problem while writing a script for a parametric study.
After changing the each parameter the model changes and and the loaction of the interested element changes based on those parameters.
Also the element number changes.
Is there any command in python script to choose the elements based on the location ? 

Thank you in advance

The Geometry of Discombinations and its Applications to Semi-Inverse Problems in Anelasticity

The geometric formulation of continuum mechanics provides a powerful approach to understand and solve problems in anelasticity where an elastic deformation is combined with a non-elastic component arising from defects, thermal stresses, growth effects, or other effects leading to residual stresses. The central idea is to assume that the material manifold, prescribing the reference configuration for a body, has an intrinsic, non-Euclidean, geometric structure. Residual stresses then naturally arise when this configuration is mapped into Euclidean space.

Implementing XFEM in ABAQUS using dynamic implicit step

Is there anybody who has implemented XFEM in ABAQUS using dynamic implicit step? My model runs fine when I use 'static, general' step but when I change it to 'dynamic, implicit' I get following error message"The following XFEM cracks are failing to correctly generate and says crack domain contains invalid element shape." Please let me know what do I need to change in the model to fix this error. 

Thanks so much for your help,

generat initial stresses ?

Hi everybody

I am a geotech engineer, I use a program Abaqus, I want to know 
when I use tow layers of soil, each layer with their properties, when i use the contact between these layers

my question is; How i generat initial stresses without discontinuity between the two layers ?
