The OptiStruct Model Checker utility allows you to check the quality of elements, properties, materials, and load steps in an OptiStruct model.
The GUI consists of four pull-down menus and a report window. The pull-down menus: File, Options, Run, and Help are described here:
|
File |
Save Report |
Allows you to select a file name and location to save the information in the report window to a text file. |
|
|
Clear Report Window |
Deletes everything from the report window. |
|
|
Close |
Exit and Close the Model Checker. |
|
|
|
|
|
Options |
Open Settings |
Allows you to retrieve settings from a data file. |
|
|
Save Settings |
Allows you to save the current settings to a data file. |
|
|
1D Element Quality Settings… |
Allows you to alter settings for 1-D element checks. The settings which can be altered are : · Minimum 1-D element length (default = 0.0) · Maximum 1-D element length (default = 20.0) |
|
|
2D Element Quality Settings… |
Allows you to alter settings for 2-D element checks. The settings which can be altered are : · Minimum 2-D element length (default = 0.0) · Maximum 2-D element length (default = 20.0) · Minimum jacobian value (default = 0.7) · Maximum warpage (default = 5.0) · Maximum aspect ratio (default = 5.0) · Minimum quad angle (default = 45) · Maximum quad angle (default = 135) · Minimum tria angle (default = 20) · Maximum tria angle (default = 120) |
|
|
3D Element Quality Settings… |
Allows you to alter settings for 3-D element checks. The settings which can be altered are : · Minimum 3-Delement length (default = 0.0) · Maximum 3-D element length (default = 20.0) · Minimum jacobian value (default = 0.7) · Maximum warpage (default = 5.0) · Maximum aspect ratio (default = 5.0) · Minimum quad angle (default = 45) · Maximum quad angle (default = 135) · Minimum tria angle (default = 20) · Maximum tria angle (default = 120) · Minimum tetra-collapse value (default = 0.5) |
|
|
Property settings |
Allows you to alter settings for property checks. The settings which can be altered are: · Shell Zero Gauge Threshold (default = 0.001) - PSHELL or PCOMP components with a thickness less than this value fail this check. · Cross Section Zero Area Threshold (default = 0.001) - PBAR, PBEAM or PROD properties with a cross-section less than this value fail this check. |
|
|
Material settings |
Allows you to alter settings for material checks. The settings which can be altered are : · Zero Density Threshold (Default = 1e-9) - All material densities must be greater than this value. · Zero Modulus Threshold (Default = 1e-3) - All modulii must be greater than this value. · Zero Poisson's Ratio Threshold (Default = 1e-3) - All Poisson's ratios must be greater than this value. |
|
|
Model Checker Settings |
Allows user to specify additional settings, can choose from the list: · Perform 1-D element checks (Default = yes) · Perform 2-D element checks (Default = yes) · Perform 3-D element checks (Default = yes) · Create sets for failed elements (Default = no) · Output % failed - element quality (Default = yes) · Output warning/error count for property checks (Default = no) |
|
|
Settings to defaults (all) |
Reset all settings to defaults. |
|
|
|
|
|
Run |
Select Tests |
Allows user to check which tests to perform from the list: · Property checks · Material Checks · Element Checks · Loadstep Checks · Default (all) |
|
|
Run Model Checker |
Performs model checking and populates the report window with the results. |
