A Relation Map has been added to RecurDyn that visually displays the relationship between various entities in RecurDyn. Selecting a body allows you to visually see all joint, force, and other elements that are connected to this body. ?Similarly, selecting a joint allows you to see all bodies that the joints connect to. The Relation Map also makes it easier to verify that connections are properly maintained after meshing a rigid body or producing a Swap Body for a flexible body. relation-map Quick View Rotation ‘Quick View Rotation’ Buttons have been added to the View Control of the Working Window. These buttons provide a very simple and convenient way to quickly rotate the view in the Working Window. Many improvements have been made in Flexible body modeling to enhance RecurDyn’s abilities for simulating MFBD (Multiple-Flexible-Body Dynamics). These include improvements to Assist Modeling for simplifying the process of creating flexible bodies, an improved Cutting Plane in the UI to help visualize the results of simulations with flexible bodies, as well as modifications to the Bushing Force element that can improve the computational speed of models that use large numbers of Bushing Force elements. Assist Modeling A large number of improvements have been made to the Mesher’s Assist Modeling to enhance its convenience and useful to users when converting MBD models into MFBD (Multi-Flexible-Body Dynamics) models. Geo Surface Contact Preservation: When Geo Surface Contact is defined on a Rigid Body, the Mesher is capable of preserving the Geo Surface Contact when the body is converted into an FFlex body. When the body is converted from a Rigid Body to an FFlex Body, the Patch Set that is required on the FFlex Body is automatically generated. Improvements to Automatic FDR Generation: When the Preserve Constraint option is used on a body that is connected with a Joint to another body, an FDR element is created. When the element is created, the Geometry Surface that is required is automatically assigned. Cutting Plane The cutting plane has been substantially improved for viewing details inside of FFlex bodies. The cutting plane is now able to show the interior regions of FFlex bodies when the Contour Display is used. There are 2 options for the Cutting Plane for viewing the interiors of FFlex bodies. Furthermore, this improved Cutting Plane functionality is available in Body Edit Mode as well. Cross Section: The elements of an FFlex body that cross the Cutting Plane are cut so that the interior regions of the elements are displayed. Element Shape: Any elements that cross the Cutting Plane are completely hidden. Only the surfaces of elements are shown. The interiors of elements are not visible in this Cutting Plane mode.
