Interactive real time processing

VisualFEA has the capability of interactive real time processing for truss and frame analysis. Interactive real time processing means that the cycle of data modification, subsequent processing, and graphical visualization of the analysis results is formed in real time. Thus, you can see the changing response as you add or modify the data.

For analysis types of 2-D truss, 3-D truss, 2-D frame and 3-D frame, interactive real time processing is the default mode. "Auto Solve" item of menu is enabled only for these analysis types. The interactive real time analysis mode can be turned on or off by checking the menu item. If the mode is turned off, the normal procedure of processing applies, as described in the previous sections.

If the mode is on, you don't have to select "Solve" item from menu. Instead, you have to designate the data item to display from menu. Whenever you add or modify the data, the processing is executed automatically, and the display of the analysis results is updated immediately.

The progress bar does not appear during processing. Furthermore, if "Instant Redrawing" item of menu is checked, the diagrams re p resenting the analysis results are automatically updated immediately after any change in the modeling data. Modification in geometries, attributes, boundary conditions, or load conditions of the model is reflected in the currently displayed diagram instantly. An example of interactive real time analysis is shown in the following figure.

The example shows that the bending moment diagram is displayed directly by selecting the corresponding menu item. There is no need to invoke explicitly the processing stage. The diagram is updated at the moment the load condition is altered. Likewise, the diagram will be changed as you modify the boundary conditions or element properties. Thus, the responses to varying external effects or attributes can be examined interactively. On the other hand, interactive real time analysis may sometimes hamper the responsiveness of the software, when the size of the problem is too large to get enough speed in processing one cycle. In such circumstances, you may suppress the options, by unchecking "Instant Redrawing" of menu. In addition, the progress bar can be shown while processing goes on, if "Auto Solve" item of menu is unchecked as well.
