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

Ph. D. position available at the University of Zaragoza, Spain
Dear colleagues:
We are looking for a Ph.D. candiate to join the group of Applied Mechanics and Bioengineering at the University of Zaragoza. The four-year PhD fellowships cover the full tuition, a monthly stipend, and health insurance.
Incomplete thoughts on mass flux and superposed RBM
Attached are some (hand-written) observations on wanting to do continuum mechanics when mass is not conserved for fixed sets of particles of the body (so, situations transcending the rocket-losing-mass type). I feel (un)comfortable with these observations, depending upon the day I think about such things.
Deadline extended: CSME International congress: Fatigue and Fracture of engineering materials
All,
The deadline to submit article for the CSME international congress has been extended to February 17th, 2012. We are organizing a symposium on fatigue and fracture of engineering materials and strongly encourage researchers around the world to submit their research articles relevant to this field.

VABS 3.6 Reduces Realistic Composite Blade Modeling to Seconds
AnalySwift, LLC, a leading provider of efficient high-fidelity modeling software for aerospace and energy composites and other advanced materials, announced today the release of VABS 3.6. This is the latest version of VABS, which is the tool of choice for efficient and accurate modeling of composite slender structures such as wind turbine blades, helicopter rotor blades, high aspect ratio wings, composite bridges, and other slender structural components.
Strain Rate Calculation in CEL
Hi!
I am trying to calculate the strain rate in Coupled Eulerian Analysis Using ABAQUS. I want to Calculate it through Plastic strain as strain rate in vuhard is not working properly. I want to fix the strain in state variable for a time period but with analysis, it is updated automatically. Is there any options to keep strain fixed for a time period?
Any idea will be highly appreciated.
Thanks in advance.

Stress Softening in UMAT
Hi all,
I am implementing the constitutive behaviour of CuAlNi shape memory alloy during uniaxial loading using UMAT. My question is that:
Stress decreases during phase transformation in our model but I can't do this in UMAT. When stress is needed to decrease, abaqus job stops and there is no change in the command window. I wonder that is there anything which I can do when stress starts to decrease in UMAT? It can be in input file or subroutine file.
Thank you.

LINKING FORTRAN AND C++ WITH ABAQUS
Dear all
I realized so many users have problems in
linking Fortran and C++ to ABAQUS to run user-subroutine codes such as
VUMAT and UMAT. I managed to collect all information (some taken from imechnica) which
is necessary to establish a proper link. These are my recommended steps :
1-Install ABAQUS
2-Install Microsoft Visual STUDIO (trial
version is good enough!) and install Intel Visual Fortran Compiler if it is not included in the Visual Studio package.
