USE_ABQ_SENS |
|
This option is obsolete and has no influence on the optimization procedure. |
SENS_CALC_MODE |
=AUTOMATIC/SOLVER/TOSCA/HYBRID |
Controls whether the DRESPs values and sensitivities should be calculated by the solver or by
the optimization system. If this option is set to
AUTOMATIC , the optimization system will
chose the best calculation mode. If HYBRID is
chosen the design response values and the corresponding
sensitivities will be calculated by solver if they are supported
and by the optimization system for all other cases. To be able
to use older versions of Abaqus
(older than 3DEXPERIENCE2017x FP1721), set SENS_CALC_MODE = TOSCA . |
SOLVER_RUN_MODE |
=AUTOMATIC/SEQUENTIAL/SIMULTANEOUS |
Controls whether the solver should be called (check out licenses, run preprocessor, solve the
modified job, output the results, shut down) in each iteration
in sequential sessions or a single/simultaneous solver session
(start the solver once at the beginning of the optimization,
communicate modifications of the model by distribution tables,
and solve the job in each iteration, shut down the solver by the
end of optimization) should be started. If this option is set to
AUTOMATIC the optimization system chooses
the best solver run mode. |
ABQ_SENS_ABSENT_SET_ZERO |
=YES/NO |
In case of using the sensitivities calculated by
Abaqus,
this option controls whether to set the missing sensitivity values to zero or not. This option should be set,
for example, when *model change command is used in the solver input file. |
FORCE_SIM_YES |
=FALSE/TRUE |
In case of using the sensitivities calculated by
Abaqus,
if mode tracking is present in the analysis this option converts any
SIM=NO command to SIM=YES in the input file. |
KEEP_SFILM |
=TRUE/FALSE |
This option turns off the modification of *sfilm card during the optimization. It
allows the user to keep the original surface film boundary condition throughout
the optimization even if the actual surface has changed. |
USE_ABQ_UNROLL |
= YES/NO/ON/OFF/SELECTIVE |
Controls the enrolling of *LOADCASEs inside a *STEP.
Note:
SELECTIVE means that the unrolling only happens if the first *STEP is a preloading step
|
NODAL_MODIFICATION |
= DISTRIBUTION_TABLE /INPUT_FILE |
Controls how node modifications from shape optimization are communicated to the FE solver. Only
usable in combination with solver sensitivities.
DISTRIBUTION_TABLE: Write node modifications only in the
distribution table.
INPUT_FILE: Write node modifications directly into the
solver input file.
|
DRESP_GROUP_OPER_AGGREGATION |
= ON / OFF |
This option controls if the group in the design response will be evaluated using the existing
Tosca algorithm or a new algorithm introduced in 2021x based on
Abaqus sensitivities.
The new algorithm provides performance benefits in case of large groups or multiple
load cases. The
default is OFF means only the existing algorithm will be used. |
