The FFlex body used in RecurDyn is a meshed FE body. For these FFlex bodies, The Merge FFlex Body function allows for a combination of multiple FFlex bodies into one FFlex body.

The Merge FFlex Body feature is located in [Flexible tab > FFlex group > Merge icon] and allows for merging two different FFlex bodies into one FFlex body. In such cases, each material property applied to the two FFlex bodies before merging is maintained.

  • Delete Tool's Unused Materials & Properties: If this option is disabled, all Material Properties are maintained. If this option is enabled, unused Material Properties in the Tool Body will be automatically deleted. If the same Material Property is applied, the Material in the Tool Body will be deleted and one Material Property will be applied.
  • Coincident Node: Select whether to use Coincident Node.
  • Search Only Selected Node Set: If you want to specify specific Nodes as coincident Nodes, you can set them by specifying a NodeSet.
  • Preview: You can preview the Consident Nodes that will be created.


With these functions, you can effortlessly generate a model for MFBD (Multi-Flexible Body Dynamics) analysis of mechanical components that involve overlapping or combined materials with distinct properties.
