sponge.function.calc_angle_pbc

sponge.function.calc_angle_pbc(position_a: Tensor, position_b: Tensor, position_c: Tensor, pbc_box: Tensor, keepdims: bool = False)

Compute angle $\mathrm{\angle }ABC$ formed by the position coordinates of three positions

$A$, $B$ and $C$ at periodic boundary condition.

Parameters

• position_a (Tensor) – Tensor of shape $(...,D)$ . Data type is float. D means spatial dimension of the simulation system. Usually is 3. Position coordinate of point $A$.

• position_b (Tensor) – Tensor of shape $(...,D)$ . Data type is float. Position coordinate of point $B$.

• position_c (Tensor) – Tensor of shape $(...,D)$ . Data type is float. Position coordinate of point $C$.

• pbc_box (Tensor) – Tensor of shape $(D)$ or $(B,D)$ . Data type is float. B means batchsize, i.e. number of walkers in simulation Size of PBC box $\overrightarrow{L}$

• keepdims (bool) – If this is set to True, the last axis will be left in the result as dimensions with size one. Default: False .

Returns

angle (Tensor), a tensor of shape $(...)$ or $(...,1)$ . Data type is float.
