Standard Reports | |
At the end of each optimization run, SIMULIA Tosca Structure generates standard postprocessing reports based on templates in the installation and OPTIONS specified in your parameter file. The results are available as vtfx file <jobname>_report.vtfx in the directory <jobname>\TOSCA_POST. SIMULIA Tosca Structure generates automatically parameter files for each standard report like in the examples below. The corresponding SIMULIA Tosca Structure command is described in detail in REPORT command specification.
SIMULIA Tosca Structure.Topology Results
Per default, postprocessing reports for topology optimization show only one case: the material distribution during the optimization. Further, the values of objective function and constraint and eventually defined variables are shown in result plots.
CONTOURPLOT ID_NAME = TOPO_MAT TYPE_PROPERTY = ELEMENT_FILL_FILTER TITLE = "Relative Material Distribution, soft elements filtered" DESCRIPTION = "TOSCA Structure.topology Optimization Result" FRINGE_RESULT = MAT_PROP_NORMALIZED FILTER = 0.05,1 ITERATION = ALL GROUP_FILE = "SAVE.onf/GROUPS.onf" END_
REPORT ID_NAME = __JOBNAME___report RESULT = "SAVE.onf/TP" MODEL = "SAVE.onf/MODEL_fem.onf" OUTPUT_FILE = __JOBNAME___report CONTOURPLOT = TOPO_MAT END_
A smoothed model can be added to the report automatically. Isovalue or target volume can be set in the OPTIONS command in the parameter file.
SIMULIA Tosca Structure.Shape Results
Standard postprocessing reports for shape optimization show two different cases: the controller input on the deformed model during the optimization as well as the absolute displacement values. Further, the values of objective function and constraint (if available) as well as the history of design response values are shown in result plots.
CONTOURPLOT ID_NAME = SHAPE_DISP TYPE_PROPERTY = NODAL_DISPLACEMENT TITLE = "Nodal Displacement from Shape Optimization" DESCRIPTION = "TOSCA Structure.shape Optimization Result" FRINGE_RESULT = DISP_OPT_VAL DISP_RESULT = DISP_OPT ITERATION = ALL GROUP_FILE = "SAVE.onf/GROUPS.onf" END_ CONTOURPLOT ID_NAME = SHAPE_CTRL TYPE_PROPERTY = NODAL_CONTINUOUS TITLE = "Controller Input on deformed model" DESCRIPTION = "TOSCA Structure.shape Optimization Result" FRINGE_RESULT = CTRL_INPUT(OPT.)eqv. DISP_RESULT = DISP_OPT ITERATION = ALL GROUP_FILE = "SAVE.onf/GROUPS.onf" END_ REPORT ID_NAME = __JOBNAME___report RESULT = "SAVE.onf/SHAPE" MODEL = "SAVE.onf/MODEL_fem.onf" OUTPUT_FILE = __JOBNAME___report CONTOURPLOT = SHAPE_CTRL CONTOURPLOT = SHAPE_DISP END_
Nodal Displacement Plots in Normal Direction
To request nodal displacement plots that show the node displacement in normal direction only, a special USER_FILE commando is required in the parameter file.
USER_FILE ID_NAME = UF_SHAPE_NORM_DISP FORMAT = ONF EL_GROUP = ALL_ELEMENTS TYPE = SHAPE_NORM_DISP FILE_NAME = SHAPE_NORMAL_DISP WRITE = EVER FILE_OPTION = VAR2 END_
For generating the plots within a TEST_SHAPE run, the dispalcements of the next iteration mus be requested and the test_shape FORMAT must be set to user defined post processing output.
USER_FILE ID_NAME = UF_SHAPE_NORM_DISP ! [...] TYPE = SHAPE_NORM_DISP_N END_
TEST_SHAPE OPTIMIZE = OPTIMIZE_SHAPE_CONTROLLER DIRECTION = GROW DISPLACEMENT = 10 INCREMENT = 5 USER_FILE = UF_SHAPE_NORM_DISP FORMAT = USER_FILE END_
Both commandos create a bunch of onf files in the SAVE.onf directory. Now, TOSCA_GUI can be used to generate vtfx plots.
SIMULIA Tosca Structure.Bead Results
Standard postprocessing reports for bead optimization show one case: the optimization displacement value on the deformed model during the optimization. Further, the values of objective function and constraint (if available) as well as the history of design response values are shown in result plots.
CONTOURPLOT ID_NAME = BEAD_DISP TYPE_PROPERTY = NODAL_DISPLACEMENT TITLE = "Nodal Displacement from Bead Optimization" DESCRIPTION = "TOSCA Structure.bead Optimization Result" FRINGE_RESULT = DISP_OPT_VAL DISP_RESULT = DISP_OPT ITERATION = ALL GROUP_FILE = "SAVE.onf/GROUPS.onf" END_ REPORT ID_NAME = __JOBNAME___report RESULT = "SAVE.onf/BEAD" MODEL = "SAVE.onf/MODEL_fem.onf" OUTPUT_FILE = __JOBNAME___report CONTOURPLOT = BEAD_DISP END_
SIMULIA Tosca Structure.Sizing Results
Standard postprocessing reports for sizing optimization show two different cases: the shell thickness change on the model during the optimization as well as the shell thickness distribution. Further, the values of objective function and constraint (if available) as well as the history of design response values are shown in result plots.
REPORT ID_NAME = GENERATE_REPORT_FILE MODEL = "SAVE.onf\MODEL_fem.onf" RESULT = "SAVE.onf\SIZING" OUTPUT_FILE = "TOSCA_POST\GENERATE_REPORT_FILE" CONTOURPLOT = SIZING_THICKNESS CONTOURPLOT = SIZING_DELTA_THICKNESS CONTOURPLOT = MODEL END_ CONTOURPLOT ID_NAME = SIZING_THICKNESS TYPE_PROPERTY = ELEMENT_THICKNESS TITLE = Thickness from Sizing Optimization DESCRIPTION = TOSCA Structure.sizing Optimization Result FRINGE_RESULT = THICKNESS ITERATION = ALL GROUP_FILE = "SAVE.onf\GROUPS.onf" END_ CONTOURPLOT ID_NAME = SIZING_DELTA_THICKNESS TYPE_PROPERTY = ELEMENT_DELTA_THICKNESS TITLE = Thickness Change from Sizing Optimization DESCRIPTION = TOSCA Structure.sizing Optimization Result FRINGE_RESULT = DELTA_THICKNESS ITERATION = ALL GROUP_FILE = "SAVE.onf/GROUPS.onf" END_
Morphing Results
Standard postprocessing reports for morphing results contain a contour plot of the OBJ_FUNC value referenced by the assigned shape optimization and the nodal displacement plots.
CONTOURPLOT ID_NAME = SHAPE_DISP_XXX TYPE_PROPERTY = NODAL_DISPLACEMENT TITLE = "Nodal Displacement from Shape Morphing" DESCRIPTION = "TOSCA Structure.shape Optimization Result...." FRINGE_RESULT = DISP_OPT_VAL DISP_RESULT = DISP_OPT ITERATION = ALL GROUP_FILE = "SAVE.onf/GROUPS.onf" GROUP = __GROUP_NAME__ END_
CONTOURPLOT ID_NAME = SHAPE_CTRL_XXX TYPE_PROPERTY = NODAL_CONTINUOUS TITLE = "Controller Input on deformed model" DESCRIPTION = "TOSCA Structure.shape Morphing Result. ..." FRINGE_RESULT = CTRL_INPUT(OPT.)eqv. DISP_RESULT = DISP_OPT ITERATION = ALL GROUP_FILE = "SAVE.onf/GROUPS.onf" GROUP = __GROUP_NAME__ END_
REPORT ID_NAME = JOBNAME_report_XXX RESULT = "SAVE.onf/TOSCA_MORPH" MODEL = "SAVE.onf/MODEL_fem.onf" CONTOURPLOT = SHAPE_CTRL_XXX CONTOURPLOT = SHAPE_DISP_XXX END_
Sensitivity Plots
To access sensitivity information, you can write them to an ONF-file which is then evaluated in a sensitivity plot. Using the following command it is possible to create all sensitivity plots and add them to your report file:
REPORT ID_NAME = sens_plots SENSITIVITY_PLOT = YES END_
The USER_FILE command writing the sensitivity data to ONF format must be in the original parameter file, because SIMULIA Tosca Structure.control must know all OBJ_FUNCs and CONSTRAINTs.For generating the ONF Data with the sensitivities inside the following statement has to be placed in the parameter file:
Sensitivity Plots for Bead Optimization
The sensitivities are written to an ONF file with the following command:
USER_FILE ID_NAME = UF_BEAD_ONF_SENS FORMAT = ONF EL_GROUP = ALL_ELEMENTS TYPE = BEAD_DATA_SENS FILE_NAME = BEAD_SENS WRITE = EVER FILE_OPTION = VAR2 END_
Instead of writing the command the corresponding macro can be included:
INCLUDE, uf_bead_sens_onf.mac
Sensitivity Plots for Topology Optimization
The sensitivities can be written in original form:
USER_FILE ID_NAME = UF_TOPO_ONF_SENS FORMAT = ONF EL_GROUP = ALL_ELEMENTS TYPE = TOPO_WITH_SENS FILE_NAME = TP_SENS WRITE = EVER FILE_OPTION = VAR2 END_
Instead of writing the command the corresponding macro can be included:
INCLUDE, uf_topo_sens_onf.mac
