Stiffness properties
Note: This is optional.
NO_REDUCTIONis applied by default.
Setting the stiffness arrays and these options will allow for IMPETUS Solver to control the critical time step calculations. If set, reduction operations (per element) will be performed for the specific data array(s).
Options for each stiffness variable:
NO_REDUCTION: No changes are made to the original valuesMAX_REDUCTION: The maximum value reduction is applied for each elementMIN_REDUCTION: The minimum value reduction is applied for each element
These reduction operations affect the following data arrays defined in
UserMatDevice struct:
stiff_shearaffectsdevice.dp_shearstiff_bulkaffectsdevice.dp_bulkstiff_xiaffectsdevice.dp_xistiff_bfacaffectsdevice.dp_bfac
Class member variables
int stiff_shear
int stiff_bulk
int stiff_xi
int stiff_bfac
Description
bool stiff_shear
Setting this property will apply reduction operations on the data.dp_shear array.
Options:
NO_REDUCTION: No changes are made to the original valuesMAX_REDUCTION: The maximum value reduction is applied for each elementMIN_REDUCTION: The minimum value reduction is applied for each element
int stiff_bulk
Setting this property will apply reduction operations on the data.dp_shear array.bulk` array.
Options:
NO_REDUCTION: No changes are made to the original valuesMAX_REDUCTION: The maximum value reduction is applied for each elementMIN_REDUCTION: The minimum value reduction is applied for each element
int stiff_xi
Setting this property will apply reduction operations on the data.dp_shear array.xi` array.
Options:
NO_REDUCTION: No changes are made to the original valuesMAX_REDUCTION: The maximum value reduction is applied for each elementMIN_REDUCTION: The minimum value reduction is applied for each element
int stiff_bfac
Setting this property will apply reduction operations on the data.dp_shear array.bfac` array.
Options:
NO_REDUCTION: No changes are made to the original valuesMAX_REDUCTION: The maximum value reduction is applied for each elementMIN_REDUCTION: The minimum value reduction is applied for each element
