PCASMType

Type of additive Schwarz method to use

Synopsis

typedef enum {PC_ASM_BASIC = 3,PC_ASM_RESTRICT = 1,PC_ASM_INTERPOLATE = 2,PC_ASM_NONE = 0} PCASMType;
 PC_ASM_BASIC        - Symmetric version where residuals from the ghost points are used
                       and computed values in ghost regions are added together.
                       Classical standard additive Schwarz.
 PC_ASM_RESTRICT     - Residuals from ghost points are used but computed values in ghost
                       region are discarded.
                       Default.
 PC_ASM_INTERPOLATE  - Residuals from ghost points are not used, computed values in ghost
                       region are added back in.
 PC_ASM_NONE         - Residuals from ghost points are not used, computed ghost values are
                       discarded.
                       Not very good.
