mindspore.ops.BondForceWithAtomEnergy

class mindspore.ops.BondForceWithAtomEnergy(*args, **kwargs)[source]

Calculate bond force and harmonic potential energy together.

The calculation formula is the same as operator BondForce() and BondEnergy().

Parameters

  • atom_numbers (int32) – the number of atoms n.

  • bond_numbers (int32) – the number of harmonic bonds m.

Inputs:

  • uint_crd_f (Tensor, uint32 ) - [n, 3], the unsigned int coordinate value of each atom.

  • scaler_f (Tensor, float32) - [3,], the 3-D scale factor (x, y, z), between the real space float coordinates and the unsigned int coordinates.

  • atom_a (Tensor, int32) - [m,], the first atom index of each bond.

  • atom_b (Tensor, int32) - [m,], the second atom index of each bond.

  • bond_k (Tensor, float32) - [m,], the force constant of each bond.

  • bond_r0 (Tensor, float32) - [m,], the equlibrium length of each bond.

Outputs:

  • frc_f (Tensor, float32) - [n, 3], same as operator BondForce().

  • atom_e (Tensor, float32) - [n,], same as atom_ene in operator BondAtomEnergy().
