Run the crank slot analysis using a flexible approximation for the Rod2 part. After defining Rod2 as a flexible body, mesh it using 3D SOLID186 elements. (At this stage, the remaining parts are still considered to be rigid.)

For more information, see Modeling Flexible Bodies in a Multibody Analysis. The input fileCrankSlot_Flexible.inp is used to perform the flexible body portion of the analysis.

The following figures show the FE representation of the flexible Rod2 part and a representation of the entire model:
