dynamic rolling contact

For those interested in a classical subject like contact mechanics, here are a couple of recent papers published in August.  One is an extension of the Greenwood Williamson theory of rough contact, and the other is a linear perturbation solution of the classical Carter rolling contact problem for a rolling cylinder, when the surface is corrugated and hence there are oscillations in both normal and tangential loads.

Hi, I am just making an entry here to introduce myself.

 I am an ethnobotanist studying the origin, domestication, and dispersal of taro, a semiaquatic herb (in nature). My role is historian to the crop, so I try to learn anything and everything I can about the plant, from all points of view.

How to combine or embed a link into an area in ANSYS?

ANSYS single cell deformation biology

Using ANSYS, I'm trying to create a single 2D cell model that has 3 components - nucleus (represented by a circular area), cytoplasm (represented by a circular area) and cytoskeleton (represented by a line). When I apply a load on the model, the link element of the cytoskeleton does not deformed whereas the rest of the solid elements (nucleus and cytoplasm) deform.  I can't find a function that i can use to glue the line to the area of interest. Does anyone know how to combine or embed a link into an area?
