Hello,

the situation you describe is usually called "axisymmetric" (to give you
some hint for better googling) and is widely used e.g. in FEM or
modelling in general to reduce 3D problem to "2D" (other similar
reductions being plane stress and plane strain).

It is currently not possible in Yade.

However, I was playing with the idea before and still it is in my TODO list :-D
Although most likely I will not ever accomplish it.

I **think** (it is really a brainstorming without any testing or evidence or estimation of needed time to make it work) that it would be possible, in C++ source code or even pure python.
After time step, you know positions of particles and can determine and evaluate the "axisymmetric" contacts and apply corresponding forces and torques to the particles.
Basically doing "manually" the job of collider and interaction loop.

The problem is also the boundary, which cannot (or it would be very
difficult) be "smooth".

Cheers
Jan
