Factory for building Smoothed Aggregation prolongators. More...
Factory for building Smoothed Aggregation prolongators.
Parameter | type | default | master.xml | validated | requested | description |
---|---|---|---|---|---|---|
sa: damping factor | double | 1.33 | * | * | Damping factor for smoothed aggregation transfer operators | |
sa: calculate eigenvalue estimate | bool | false | * | * | Force calculation of eigenvalue estimate during prolongator smoothing | |
sa: eigenvalue estimate num iterations | int | 10 | * | * | Number of power iterations to estimate max eigenvalue | |
A | Factory | null | * | * | Generating factory of the matrix A used during the prolongator smoothing process | |
P | Factory | null | * | * | Tentative prolongator factory (should be a TentativePFactory object). Note that if "P" is not provided the FactoryManager tries the factory which is generating the variable "Ptent" as input for "P". In the standard case using the default settings this is the non-smoothed tentative prolongation operator. |
The * in the master.xml
column denotes that the parameter is defined in the master.xml
file.
The * in the validated
column means that the parameter is declared in the list of valid input parameters (see SaPFactory_kokkos::GetValidParameters).
The * in the requested
column states that the data is requested as input with all dependencies (see SaPFactory_kokkos::DeclareInput).
After SaPFactory_kokkos::Build the following data is available (if requested)
