Name

Mesh>Constant Area

Type

Stretching

Defined in

Faces

For a given triangle ( t ), compute the contribution from the surface tension due to changes in the surface area.

\[U_t = \frac{1}{2} \sigma \left(A - A_0\right)^2\]

Where:

  • ( A ) is the current area of the triangle

  • ( A_0 ) is the native (given) triangle area

  • ( sigma ) is the surface tension

Python calling#

evolver.add_force("Mesh>Constant Area", {
    "sigma": {"1": str(E_value)}
})
