pymem3dg.boilerplate.prescribeGaussianPointForce(vertexPositions: ndarray[Any, dtype[float64]], vertexDualAreas: list, time: float, geodesicDistances: list, Kf: float, std: float, tau: float)

form function that generate external force on a single vertex following a Gaussian distribution of geodesic distance

Parameters:

• vertexPositions (npt.NDArray[np.float64]) – vertex position matrix of the mesh

• vertexDualAreas (list) – vertex dual area. Unused

• time (float) – time of the simulation. Unused

• geodesicDistances (list) – geodesic distance centered at the vertex

• Kf (float) – force magnitude coefficient

• std (float) – standard deviation of the Gaussian distribution

• tau (float) – time scale of decay in the form of exp(-time/tau)

Returns:

vertex force matrix

Return type:

(npt.NDArray[np.float64])
