Autodesk inventor 2018 stress analysis free.Stress Analysis Settings reference |
Create a simulation | Inventor | Autodesk Knowledge Network.
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. Either the mesh is too refined or there are incorrect settings. Please share your files here so forum experts can help take a look.
Assembly is located: TMNG. I took a look at your file. It appears that there is a sub-floor on top of a metal framework. But, also in the metal framework, there is engineered wood trusses. I am not so sure how to handle the wood trusses in Inventor Stress Analysis.
In order to get accurate results, all materials in Inventor must be isotropic. Since that is not the case with a wood truss You may be able to exclude all the wood trusses from the analysis. This will give you an idea about how the metal beams will react to the load.
The wood trusses will have to be looked at differently. In general analysis of this kind of structure, like any civil engineering structure, is not limited to FEA calculation regardless of kind of the calculation.
There are numerous other aspects that must be considered and that are generally omitted in FEA calculations due to complexity, and they are dealt using safety factors and various modelling approaches and assumptions used for preparing analytical models.
Usually Engineering studies take at least 4 years and additional years of practice to get your design license depending on country so it is not possible to answer all questions end explain everything in this thread that would concern design of this structure if you do not have any civil engineering education and are not familiar with codes.
I have done a 4 year study in mechanical engineering SVE and am currently in my second year of Engineering bachelor. My knowledge of stress analysis is very limited as i have never used these before during my education. I live in the Netherlands and the structure should be placed in a private workshop of a friend of mine.
It is not going to be use for any company use, just some storage and other things. We are certain the load will never come close to anything above kg per square meter.
If i can deliver the owner of the building some schematic drawings of the design and somewhat of a stress analysis owners words, not mine then we can pretty much build what we want he said. I thought inventor was able to distribute a load evenly over the entiere surface, but i just don't know how to.
Ofcourse i learned a lot about calculating stress and what not during my education but i we always seem to have focused on singular beams and more simplified versions of problems. Also the books i have mainly Hibbeler don't really give me an answer either. This is steel so it should follow Eurocode 3 as you are in Europe. Since you are doing Engineering studies I understand I am sure you have used this code already.
I will download your model and give you some advice. Is is possible to add something? What are requirements for access below? There can be no colums beneath the floor, only on the sides. The structure can be connected to a stone wall on one side. The 2 crosses should precent any flex.
Acces will be added later in form of a simple wooden staircase, no forklift acces needed. All materials will be brought up by hand. On the ribbon, the Stress Analysis tab contains a series of named panels, each with one or more commands that are grouped by functionality.
Manage panel. Material panel. Constraints panel. Loads panel. Contacts panel. Prepare panel. Mesh panel. Solve panel. Result panel. Display panel. Report panel. Settings panel. Parent topic: About Stress Analysis. Create Simulation. Displays the Create New Simulation dialog box, where you define the new simulation.
Parametric Table. Displays the Parametric table dialog box, where you define the table parameters. Displays the Assign Materials dialog box, where you define the materials to override the original material definition. Displays the Fixed Constraint dialog box, where you select geometry and further define the constraint.
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.

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 Compute Preloaded Modes Computes stress on a model, and then computes modes for the prestressed condition.
Enhanced Accuracy Increases the accuracy of the calculated frequency values by an order of magnitude Contacts Tolerance Specifies the maximum distance between faces or edges to consider in automatic detection.
Faces or edges falling outside the distance are eliminated from participating in automatic contacts. Type From the list of contact types, select the type to generate automatically when the simulation builds contacts. You can edit individual contacts and change the type later Normal or Tangential Stiffness Specifies the equivalent normal stiffness value. Applicable to Spring contact only. Note: Normal and tangential directionality is based on the best approximation between the two faces that follow each other in a parallel way.
Examples are parallel planes, concentric cylinders, and so on. Otherwise it can be ambiguous. Model State tab Representations Each assembly simulation maintains an association to each representation type. As you activate different simulations, the corresponding representation is activated for that simulation.
You can change the representation association at any time. If you do so after you run a simulation, the results can be out of sync. If so, rerun the simulation. Does not paste Simulation, Mesh, and Convergence settings, and Exclude states. Create a simulation Open the model you want to analyze. By default, it opens in the modeling environment. On the ribbon Environments tab Begin panel, click Stress Analysis. Note: You cannot enter the Stress Analysis environment while performing an edit in place on a part.
However, you can create a Motion Loads simulation static analysis in an assembly. You can analyze a single part for the motion load. Activate a simulation In the browser, double-click the inactive simulation node.
