Software to generate x-ray diffraction pattern

Submitted by cdeng on

Hello all,

 Does anyone know any software that can generate x-ray diffraction pattern for polymer? I used to have Cerius2 which can do the job very well, but unfortunately the license expired some months ago and I am looking for some alternative software that can do similar job. Right now I have all the structures saved in .msi format. Any suggestions would be appreciated, thanks a lot!

FEMLAB-COMSOL Multiphysics

Submitted by Catherine on

Hi,

I am a PhD student and I have just started to work on FEMLAB and was just wondering if someone could help me with FEMLAB. I am using at the moment the PDE modes-Weak forms to solve flow over topography using the lubrication equation. I have implemented the lubrication equations into the subsomain settings and set the boundary conditions  but i do get wrong results. Could you please advice where i might have done wrong.
Any suggestions will be really appreciated.
Many thanks
Catherine

 

Some loud (and crazy) thinking on automobiles...

Submitted by Ajit R. Jadhav on

At iMechanica, almost none talks about topics from structural dynamics and design, theory of machines, automotive mechanics, space mechanics, etc.

Let me help correct this situation by raising two questions below. Well-thought answers from any individual are welcome.

First, some background for the questions.

Research Programmer in Computational Mechanics

Submitted by karelmatous on

The Computational Science and Engineering Program of the University of Illinois at Urbana-Champaign is seeking highly qualified candidates for two research programmer positions. The positions are in the general area of Computational Solid Mechanics. Successful candidates will develop and implement parallel computational tools. Candidates should be able to interact with faculty and students from a wide variety of UI engineering and science departments, and be prepared to work closely with U.S. government and industry researchers.

User subroutines in ABAQUS

Submitted by bananth on

Hello all,

I am new to this. I got a couple of good inputs from this site, so I thot I would join too. I am a PhD student in Clemson univeristy. I am using ABAQUS for my research. Let me get to the question quickly. There are two variables that you can define in a user subroutine called TOL and HTOL. What are these and how can I know more details about this. Any inputs will be appreciated.

 

Thanks
