rotating cylinder
i want to simulate a rotating cylinder containing fluid . and this whole cylinder is also rotating about an axis which is out side the cylinder..any one can help me out?

The damping ratio, used in quasi-static problems, such as sheet forming, stamping, forging, is that role, b, shown in the following equation
Ma+bCv=P-F
For the problems mentioned above, the value of b is about 0.1. if dynamic explicit method is employed, the simulation may encounters steady problem, while convergence problem for implicit method employed. I think, you can search some articles on damping in sheet metal forming, then you will understand the effect of this damping ratio.
Laser machining of composite materials..
hai
can we do laser machining of composites materials like glass fiber etc.. from simple laser machine or we have to use special fiber laser for this..please through some light on this topic....
Pleased to see
I'm pleased to see that over 600 of you have at least read some of my comments and I wouldn't be surprise if not all of you read through to the end.
How do Italian Universities compare with British Universities, and the importance of Charles Dickens.
Mike Ciavarelli and I discussed the possibility of doing a comparison of Italian and British Universities. On reflection, I could not decide where to begin but wrote the attached. It is part personal experience, part history and part Charles Dickens who was born 200 years ago today. If you don't understand the connection, read on.
The Cost of Knowledge

If research projects are funded by public money, shouldn't their
results be available to the public at a reasonable price? or even free
of charge?
To prevent the monopolization of the scholarly record, read, think, and, hopefuly, support this cause. It is all I ask.
PCB Thermal simulation
Hi guys, I'm a Telcommunication Engineer and I'm looking for an open source software to perform thermal simualiotn on a PCB (printed circuit board) with some LDMOS transistor installed to better understand the thermal behaviour.
Can you plese suggest me once?
Thanks
Davide

HI SIR/MADAM,
THIS IS SURYATEJASWI , MAM/SIR I NEED TO KNOW HOW DO I USE TIE CONSTRAINTS TO TIE UP THE SURFACE SKIN OF A CURVED PANEL AND STRINGER IF THEY ARE TO BE A SHELL ELEMENTS... PLZ SUGGEST ME WITH THIS PROLEM AND ALSO WITH MY PROJECT..
HOPE FOR THE BEST NEED
