Stress Analysis Settings reference | Inventor | Autodesk Knowledge Network
The Stress Analysis settings are applicable on a per document basis. These settings define the defaults for all new simulations. If you change the settings while working in a simulation, the simulation is not affected. Only simulations you create after you change the settings are affected. You can override the global settings in a single simulation by changing the simulation properties. If the Stop Criteria is met, the solve process stops before the maximum number of refinements.
If the number of refinements is satisfied before the Stop Criteria is satisfied, the process stops. The value of 0. Contact Defaults Tolerance Specifies the maximum distance between faces or edges to consider in automatic contact detection. Type Specifies the default contact type. Normal Stiffness and Tangential Stiffness Specifies the default value for the input normal.
This attribute affects how loads are transferred between surfaces. Available only for spring contact types. Excluded Components Shell Connector Tolerance Specifies the maximum ratio between shell gap and shell thickness used to bridge gaps within a midsurface.
These gaps are connected using connectors. A connector is a system generated contact that helps to consider the midsurface as physically connected even when it has gaps.
Display as : Specifies the default visibility settings for excluded components. Invisible Component visibility is turned off. Transparent Uses the disabled component visibility characteristics Shaded Uses the standard shaded component settings. The default value is 0. Generally, it is best to keep this number below 5, ideally 3 or 4. The default value is Detect and Eliminate Rigid Body Modes Removes the rigid body modes in problems where not enough constraints are defined, but they have a balanced load with a valid elasticity solution.
Separate Stress Across Contact Surfaces Specifies whether to have explicit representation of discontinuous stress across the contact interface in the FEA formulation. Some components of the stresses can be discontinuous due to different materials of the contacting parts. Note: When selected, deactivates averaging of results across contact surfaces. When cleared, no OLE link is established. This setting applies to ALL simulations in the document.
Stress Analysis Settings – Meshing tab Meshing Defaults Average Element Size as a fraction of bounding box length Specifies the fraction of the longest axis of the model between adjacent nodes. A smaller value creates smaller mesh elements. Minimum Element Size as a fraction of average size Specifies the fraction of the average mesh size to place the closest pair of element nodes.
Grading Factor Specifies the maximum ratio of adjacent mesh edges for transitioning between coarse and fine regions. A smaller grading factor produces a more uniform mesh.
Maximum Turn Angle Specifies the maximum angle for arcs from 1 through 90 degrees. A smaller angle produces smaller mesh elements. When cleared, produces meshes with straight elements which can lead to less accurate representation of the model. Assembly Options Use Part-based Measure for Assembly Mesh Specifies that part mesh sizes in the assembly are to be like their part based context the part outside of the assembly context.

Inventor Frame Generator Freestanding Flooring Stress Analysis Hi, But i just cant seem to figure out how to make a good stress analysis. I searched for tutorial videos on youtube but none of them have something that.

Understand how to create and maintain stress analysis files and their relationships. A part or assembly document can maintain one or more simulations. Each document can have any number of simulations. The simulation result files, which can be large, are maintained separately and link to the part or assembly document unless you specify otherwise.
The save action saves all of the stress analysis information in the model file as well, and maintains file relationships.
Stress analysis input and results information, including loads, constraints, and all results are also saved in separate files. The simulation files are unique to a given model and simulation. Simulation files are stored in a dedicated folder of the same name as the model file. By default, OLE links are created to each of these files. You can turn off the links by changing the option. If simulation files are relocated or missing when you first open a model, the Resolve Link dialog box displays.
Either browse to the location of the simulation files, or choose to skip them. If you skip the files, the Simulation environment can recompute the files, if necessary. The stress analysis operation creates files that contain the stress analysis information.
The files live in the document hierarchy beneath the component. Simulation file behaviors:. Hierarchy of simulation folders:. Create and use analysis files Set up stress analysis information in a simulation. Save the part or assembly, which also saves the stress analysis information in the model file.
Understand file relationships The save action saves all of the stress analysis information in the model file as well, and maintains file relationships. Resolve missing files If simulation files are relocated or missing when you first open a model, the Resolve Link dialog box displays.
Understand file structure for Stress Analysis The stress analysis operation creates files that contain the stress analysis information. A simulation creates: A folder with the same name as the assembly or part file.
In the Stress Analysis folder, a GUID folder unique identifier , to prevent naming collisions between assembly and part file names. If you rename a simulation, the folder renames accordingly. Illegal characters are changed to an underscore. Where naming collisions occur, one of the simulations receives an index number enclosed in parentheses. Parent topic: About Stress Analysis.
