hysop.backend.device.opencl.operator.external_force module¶

class hysop.backend.device.opencl.operator.external_force.OpenClSpectralExternalForce(Fext, **kwds)[source]¶

Operator to compute the curl of a symbolic expression.

Create an operator that computes the curl of a given input force field Fext.

Only the following configurations are supported:: dim nb_components | dim nb_components

vorticity: 2 1 | 3 3

What is computed:: force = curl(Fext) by using a spectral backend Fmin = min(force) Fmax = max(force) Finf = max(abs(Fmin), abs(Fmax)) W += dt*force

where Fext is computed from user given ExternalForce.

Parameters:

vorticity (hysop.field.continuous_field.Field) – Continuous field as input ScalarField or VectorField. All contained field have to live on the same domain.
Fext (hysop.operator.external_force.ExternalForce) – Expression of the external force.
F... (TensorParameter or boolean, optional) – TensorParameters should match the shape of tmp (see Notes). If set to True, the TensorParameter will be generated automatically.
variables (dict) – dictionary of fields as keys and topologies as values.
kwds (dict, optional) – Extra parameters passed towards base class (MultiSpaceDerivatives).

Notes

If dim == 2, it is expected that:: vorticity has only one component Fext has 2 components
Else if dim == 3:: vorticity has 3 components Fext has 3 components

class hysop.backend.device.opencl.operator.external_force.SymbolicExternalForce(name, Fext, diffusion=None, **kwds)[source]¶

Specify an external force as a tuple of symbolic expressions.
