The _mbd.xml file is a MotionSolve XML file from a multi-body dynamics analysis.

File Creation

This file is created when a multi-body dynamics subcase is executed.

File Contents

The file format is documented in the MotionSolve manual. The purpose is the communication between the OptiStruct core and the integrated MotionSolve. This file, together with the <BODY_NAME>.h3d files, forms a full representation of the multi-body dynamics model which can be run separately in MotionSolve.
