Detailed Description
Class CFStrategy is an abstract class that provides an interface for specifying the details of a complex fluid model.
Derived classes must implement the computeRelaxation and computeStress functions.
The patch data index specifying either the conformation tensor or the square root or logarithm of the conformation tensor is given to the class. The function setDataOnPatchHierarchy is called by the advection diffusion integrator and expects the relaxation tensor.
Member Function Documentation
◆ computeRelaxation()
|
pure virtual |
Compute the action of the relaxation operator, given the conformation tensor.
The parameter evolve_type determines the form of the tensor provided in C_idx. A helper function to convert from the data stored in C_idx to the conformation tensor is provided by convert_to_conformation_tensor.
The symmetric tensor in patch data index C_idx is stored using Voigt notation.
Implemented in IBAMR::CFRoliePolyStrategy, IBAMR::CFOldroydBStrategy, and IBAMR::CFGiesekusStrategy.
◆ computeStress()
|
pure virtual |
Convert the conformation tensor to the stress tensor.
This conversion should be done in-place. The conformation tensor is provided in the patch index sig_idx with ghost cells filled. Implementations of this function MUST provide correct ghost cell information in sig_idx.
Implemented in IBAMR::CFRoliePolyStrategy, IBAMR::CFOldroydBStrategy, and IBAMR::CFGiesekusStrategy.
