fedoo.constitutivelaw.PoroFluidProperties.get_mobility

PoroFluidProperties.get_mobility(J=None, sv=None)

Return the isotropic mobility tensor k(J) / mu_f as a 3x3 list.

Parameters:

• J (ndarray or None) – Jacobian det(F) at gauss points. Required when permeability is a callable. Ignored for constant permeability.

• sv (dict or None) – State-variable dict (forwarded to callable permeability models that may depend on other internal variables).

Returns:

Mobility tensor [[k/mu, 0, 0], [0, k/mu, 0], [0, 0, k/mu]].

Return type:
