BendingRigidity¶

class hoomd.md.mesh.bending.BendingRigidity(mesh)¶

Bending potential.

BendingRigidity specifies a bending energy applied to all mesh triangles in mesh.

\[U(i) = \frac{1}{2} k \sum_{j \in \mathrm{Neigh}(i)} ( 1 - cos(\theta_{ij}))\]

with \(\theta_{ij}\) is the angle between the two normal directors of the bordering triangles of bond \(i\) and \(j\).

Example:

bending_potential = hoomd.md.mesh.bending.BendingRigidity(mesh)
bending_potential.params["mesh"] = dict(k=10.0)
