class felupe.SolidBody(umat, field, statevars=None)

Bases: object

A SolidBody with methods for the assembly of sparse vectors/matrices.

class felupe.SolidBodyNearlyIncompressible(umat, field, bulk, state=None, statevars=None)

Bases: object

A (nearly) incompressible SolidBody with methods for the assembly of sparse vectors/matrices based on a MaterialTensor with state variables.

The volumetric material behaviour is defined by a strain energy function.

\[U(J) = \frac{K}{2} (J - 1)^2\]

class felupe.StateNearlyIncompressible(field)

Bases: object

A State with internal fields for (nearly) incompressible solid bodies.

h(parallel=False)

Integrated shape-function gradient w.r.t. the deformed coordinates x.

v()

Cell volumes of the deformed configuration.

class felupe.SolidBodyGravity(field, gravity, density)

Bases: object

A SolidBody with methods for the assembly of sparse vectors/matrices.

update(gravity)

class felupe.SolidBodyPressure(field, pressure=None)

Bases: object

A hydrostatic pressure boundary on a SolidBody.

update(pressure)

class felupe.PointLoad(field, points, values=None, apply_on=0, axisymmetric=False)

Bases: object

A point load with methods for the assembly of sparse vectors/matrices.

update(values)

class felupe.Step(items, ramp=None, boundaries=None)

Bases: object

A Step with multiple substeps, subsequently depending on the solution of the previous substep.

generate(**kwargs)

Generate all substeps.

class felupe.Job(steps, callback=<function Job.<lambda>>, filename=None)

Bases: object

A job with a list of steps.
