Learn how to create and work with the analytical model for structural analysis and design.
Create an analytical model automatically with Analytical Automation Revit as you work use Analytical Automation to keep the physical model and analytical model in sync. You export the analytical model to the analysis and design software.
| Term/Concept | Definition |
|---|---|
| Analytical Model | A representation of the structural physical model consisting of analytical elements, geometry, material properties, and loads. It is created automatically while creating the physical model. You export the analytical model to the structural analysis and design software. |
| Analytical Automation | Tool used to generate and update analytical models from physical models or generate an udate a physical model from an analytical model. |
| Analytical Tolerances | Values used to create an analytical mode from a physical model. tolerance value will consider elements within the tolerance as "connected". |
| Analytical Element Properties | The instance parameters that you can use to modify the physical model when updated using Analytical Automation. |
| Select Elements and Run Automation | Use the tool to select elements from a physical or analytical model and run the tool to update the model with changes.. |
To perform a structural analysis on your model, you must first create an analytical model. This view represents the physical model of the design. Use this as the basis to create the analytical model.
On the analyze tab, use the tools to manually create an analytical model or use Analytical Automation to automatically generate the analytical model from the physical model. In this example we have a physical model, so select Physical to Analytical for Buildings.
First set tolerance between analytical elements and the tolerance to the nearest level. In both cases we will set the value to 350mm. Elements within this tolerance will be considered connected. Now set the order for the creation of analytical elements. Here we will create the columns first, then the beams, and then the walls. This order will align the beams to the columns and then the walls to both the columns and the beams.
Now click Select and use a window to select the elements from the physical model that will be used to create the analytical model then click run to create the analytical model. Once complete, you will see the analytical model elements created. The analytical model created is linked to the physical model. When you select an analytical element, click Highlight Association to see the linked physical model element. The parameters of the two elements are linked but not automatically propagated. For example, when the section of the is changed in the analytical model the change is not seen in the physical model.
Run the Analytical Automation to see the change. This time we are going from the analytical model to the physical model, so click back and then click Analytical to Physical for Buildings. Be sure the option to Update geometries of associated physical elements is set to true. Click select, select the column, and click run. Go back to look at the physical model and you see the physical model has been updated.
If the physical geometry changes like the floor element is modified, run the automation again to update the analytical model. Use Analytical automations to create and update both physical and analytical models as you do your work.
