Preferences: Inspire Form

Define preferences for General, Feasibility, Blank Nesting, and, Tryout.

General

Model Setup
Preference Description
FE mesh feature angle Enter a value for the FE mesh feature angle. The default value set by Inspire Form is 10.
FE edge feature angle Enter a value for the FE edge feature angle. The default value set by Inspire Form is 10.
Materials
Preference Description
Material library Enter a default path to the material library .xml file.
Run Options
Preference Description
Run in model directory Enable this option if you want to store run history in the directory where the model is located rather than the run history path.
Run history path Enter a default path to the directory where the run history is saved.
FLD marginal curve offset method Select Absolute or Relative method to determine offset amount between failure and marginal lines.
FLD marginal curve offset value (%) Specify the amount of offset between failure and marginal lines.
FLD loose material bound (%) Specify the amount of plastic strain to determine possibility of oil canning on part.
Die Design
Preference Description
Studio executable Enter the path to the Studio executable.
Report
Preference Description
Report template The path to the master template for reports.

Feasibility

Analysis
Preference Description
Friction Enter a value for the friction coefficient.
Shell solution Select to extrapolate the strain values to the top and bottom surfaces of the blank.
Output stamping in CAE solver formats Enable this option to output results in DYNA, RADIOSS, and OptiStruct formats in addition to standard formats.
Note: These solver results are used in Springback analysis only by default.
Marginal draft angle Enter a value for the marginal undercut draft angle. The default value set by Inspire Form is 10.
Default Element size Choose from Coarse, Medium, Fine, Custom Uniform Mesh or Custom Nonuniform Mesh. For the Custom Uniform Mesh option, you can define a default uniform element size (mm). For the Custom Nonuniform Mesh option, you can define:
  • Min. element size
  • Max element size
  • Chordal deviation: Enter the perpendicular distance between the actual curve and the approximating line segments.
  • Feature angle: Enter the angle between the element normals.
Smooth the flat blank edges Enable this option to smooth the mesh boundaries when the blank is created.
Select all free edges for drawbead by default Enable this option to automatically highlight all free edges so that you can easily select them when creating drawbeads.

Springback Solver Use the dropdown menu to select the solver you would like to use for Springback analysis. Choose from the following options:
  • RADIOSS
  • Optistruct(default)
Analysis Legend Colors Description
For each result type Choose the legend colors for plotting results.

Blank Nesting

Preference Description
  • Max Coil Width
  • Min Coil Width
  • Coil Pitch
  • Part to Part Gap
  • Part to Edge Gap
  • Carrier Width
  • Part to Carrier Gap
 Enter a value.
Note: If no value is entered, the coil width and pitch are optimized for maximum material utilization.
  • Part to Edge Gap
  • Sheet Width
  • Sheet Length
 Enter a value.
Note: Sheet width and length are required for nesting on a given sheet stock.
Top # of Results Top number of results to published in the report.
Export nested layout in .dxf file format Set the export format to .dxf.
Preference Description
Currency Choose the monetary currency by country.

Tryout

Preference Description
Enable Tryout ribbon on startup if license permits By default, the Tryout ribbon is enabled. Choose to disable it if you want to reduce the number of units drawn.
Setup
Preference Description
Automatic tool positioning Enable this option to automatically position the tools and blank relative to the bottom die during manual or automatic identification. This option is selected by default.
Tool offset factor (*thickness) Default factor for automatic tool creation, spacer, and tool close position.
Analysis
Preference Description
Marginal draft angle Enter a value for the marginal undercut draft angle. The default value set by Inspire Form is 2.
Default element size Choose from these options:
  • Coarse: default
  • Medium
  • Fine
  • Custom: Enter a value for the element size.
  • Adaptive: Enter a value for the minimum element size and the maximum adaptive level. During the forming process, this option refines the mesh to the maximum level that is specified in order to capture all of the features of the die geometry. The elements are refined to the minimum element size that is specified.
Gravity mesh coarsen level Select a custom level to use for Coarse Mesh Gravity to speed up analysis in the Gravity stage.
Tool mesh parameter estimation Select Individual tool to estimate mesh size based on the smallest edge for each individual tool, or All tools to estimate based on the smallest edge across all tools.
Geometry cleanup Select this option to remove imprints and duplicate surfaces and edges before running a simulation.
Solver run mode Choose:
  • MPI: Message Passage Interface (default) runs on all of the physical cores in your system.
  • SMP: Symmetric Multiprocessing runs on all of the processors in your system.
Number of local CPU cores Select Custom to enter a value to specify the number of CPU cores allocated to run an analysis.
Output stamping in CAE solver formats Enable this option to output results in DYNA, RADIOSS, and OptiStruct formats in addition to standard formats.
Note: These solver results are used in Springback analysis only by default.
Failure strain Enter a value for failure strain.
Remote Server
Preference Description
Number of CPU cores Enter a value to specify the number of CPU cores the server allocates to run an analysis. Default = 16.
Number of CPU cores per node Enter a value to specify the number of CPU cores per node that exist in the remote server. Default = 16.
Memory allocated to the solver (MB) Memory the server allocates to run an analysis. Default = 8000.
