2D simulation using Esys-Particle

Asked by Xavier Thurman

Hi,

I am a new user of Esys-Particle.
I have a simple question on doing a 2D simulation using Esys-Particle. 2D simulations in PFC consists of lots 2D disks, and 2D simulations in YADE consists of 3D spheres whose DOFs were blocked in z directions. Thus, my question is whether 2D disk can be used to create 2D simulations in Esys-Particle ?

Thanks and regards,
Xavier

Hi Xavier,

In ESyS-Particle it is possible to do 2D simulations. You need to call LsmMpi.force2DComputations() somewhere in your script. This will do 2 things:
- it will fix the degrees of freedom associated with the z-axis (z-translation, rotations around x- and y- axis)
- it will change the mass and inertia parameters of the particle from those for a 3D sphere of a given size and density to those of a unit length cylinder of the given radius and density - which is equivalent to a 2D disc

See also section 3.4 in the Tutorial.

Thanks SteffenAbe, that solved my question.
