Post-doctoral position in the Maddocks group at EPFL

Assistantship in the Maddocks group at the EPFL

A position is available to work on a combined analytical, numerical and experimental study of uniform elastic rods in two contexts:

1)  the characterisation of helical equilibria, including stability properties, in both the cases of self-avoiding and self-contacting configurations,


2) the equilibria of knots in the presence of friction.

[FEM] How we are using shell geometry properties in time of calculation?

Choose a channel featured in the header of iMechanica: 


I'm interested in methods and approaches for FEM, that are used for taking into account the shell geometry properties (curvatures, quadratic forms) in time of calculation. I'm not telling about NURBS, the shells are defyned by analytical expressions: sphere, Monge surfaces, Joachimstahl surface. In Zienkewich book they are use the flat elements, but in time of calculation they don't use the shell geometry, only for mesh generation. Maybe someone somehow have used in shape functions the coefficients of quadratic forms...

Postdoctoral position at the University of Oxford: Hierarchical scaling, structure, and mechanics of filamentary assemblies

A two-year postdoctoral position is available at the Oxford Centre for Collaborative Applied Mathematics (OCCAM) to work with myself on the mechanical and geometrical analysis of filament assemblies with application to biological systems. Details and Further Particulars can be found at

Spur gear geometry



I am a PhD student at Brunel University conducting my research on the noise and vibration attributed to spur gears in contact. I would like to ask for help from anyone who is an expert on gears for their opinion or direction in terms of reading material or thoughts on the limitations and design constraints of spur gear geometry. 


How to know the line/node/keypoint number in ANSYS

 I need to do the modelling in a command file instead of through the ANSYS graphinc interface as I need to try out different configurations and automatically run it in ANSYS. My question is:

 Say I create a rectangular geometry using the BLC4 command:


I need to load the structure using the DL command? How do I know which side of the rectangel is assigned which line number? Can I control this? Is it consistent?
