Requires: IES VisualFoundation
There are two independent ways that VisualAnalysis and
can work together to help you solve problems. The tools are not completely
integrated or interactive.
VisualFoundation is sold separately by IES. To learn more

- You can Export from VisualAnalysis using the Foundation Design feature.
- VisualFoundation can automatically create a VisualAnalysis project file (.vap) during analysis.
Foundation Design (Export from VisualAnalysis in to VisualFoundation)
Foundation Design allows you to export geometry and reactions from VisualAnalysis to set up a mat footing in VisualFoundation. You may quickly generate a footing geometry for one or more columns from the VisualAnalysis project. The column locations are automatically imported and the reaction-forces from VisualAnalysis service load cases are brought into VisualFoundation as loads. Foundations created in VisualAnalysis (using the (for VisualFoundation) feature are kept “simple", omitting detailed FEA modeling of the mat foundation (just supported nodes). VisualFoundation provides foundation-specific checks and targeted design support from VisualFoundation.
How does “Foundation Design" (for VisualFoundation) work?
1. Select one or more supported nodes in your
project (after an analysis is performed).
3. Run an analysis, analyzing all the Service Load Case to obtain reaction forces at nodes.
4. With the foundation selected, use
5. This VisualFoundation project can then be modified, and design checks can then be performed. You must SAVE this project to create a .vfp file that can be opened for future use.
6. When you exit VisualFoundation, the “Foundation" in VisualAnalysis is updated with a new boundary and thickness.
7. You can report a “Foundation Table" which lists all the footings by name, their thicknesses, area, and which columns are supported. You might use this to help you coordinate with any saved VisualFoundation project files.
Go to Load Case Manager to enable analysis for all your service load cases (they may not be enabled by default). On the Service Case tab, select each service case that contains loads, and check the box titled "Include in analysis".
What are the Limitations of “Foundation Design" from VisualAnalysis?
- Your support nodes must lie in a plane
- Only member elements are exported as columns to VisualFoundation (walls or columns modeled out of plate elements do not export).
- You cannot create a multi-part footing or multi-thickness footing directly from within VisualAnalysis
- You cannot "edit" or update the Foundation from VisualAnalysis. If you try to Design the foundation again it will simply create a new project in VisualFoundation, each time you choose the command.
- You cannot open any VisualFoundation project you created (either from VA or not) and somehow “update" VisualAnalysis with changes you make. The design integration is strictly an export from VisualAnalysis to VisualFoundation.
- If you create a multi-part footing in VisualFoundation, only the “outside boundary" is shown in VisualAnalysis.
- The details of the foundation are not shown or reported in VisualAnalysis, just a “pretty picture" and a thickness.
- You cannot choose when VisualAnalysis is updated from VisualFoundation, it happens when you exit VisualFoundation (and only if it was launched from within VA).
Using the .VAP Files Created by VisualFoundation
You can use the VisualAnalysis project file created by VisualFoundation to start a more sophisticated finite element analysis of your foundation using VisualAnalysis. You might use this project file look at horizontal forces on piles or to perform a dynamic analysis—neither of which is supported in VisualFoundation. VisualAnalysis also provides more advanced capabilities for designing grade beams, and foundation elements. The VisualFoundation project will also help you understand what VisualFoundation does for you behind the scenes in building the model to analyze. IES uses this project file to help validate VisualFoundation.
VisualFoundation can create a .vap
when you run an analysis in VisualFoundation. The file is created
with the same name and in the same folder as your VisualFoundation
project file. Any existing .vap project file is
replaced with a new one after each analysis—it represents the last state of your
project at the time of analysis. If you modify your VisualFoundation
project after an analysis, those changes will not be reflected in the .vap file.
Changes made to the .vap file cannot be exported back into VisualFoundation.
