When you perform modeling, you often encounter a situation where you need a slightly deformed shape.
In this case, you can create a CAD file that contains a deformed object from the beginning and apply mesh on the object. But, you can also perform dynamic analysis on a straight object by using simple force/contact and save a deformed object generated during the analysis.
To do so, you need to save a deformed geometry of a flexible body separately.
For this purpose, RecurDyn provides the following two methods.
1) Extract (System button -[Extract])
Save the animation displayed on the screen as an rdyn file.
At this time, the deformed geometry of the flexible body as well as its stress are saved together.
If you extract the model at 0.45 seconds, the flexible body of the newly saved (extracted) model has an initial condition (0 second) that is the same as that of the original model at 0.45 seconds.
2) Export Mesh Data ([Flexible] - [FFlex] - [Export Data])
Save a mesh file that was created based on the deformed geometry of a specific frame. (Nastran or ANSYS format)
At this time, you can also save the properties, materials, and boundary conditions of the mesh.
Thus, the saved mesh data can be imported to RecurDyn again or can be used in other FEA software.
