This study shows how to utilize the CATIA V6 Dynamic Behavior Modeling (DBM) software environ-ment for the purpose of co-simulation of physical mod-els. The implementation of a co-simulation using Building Controls Virtual Test Bed (BCVTB) is demonstrated and the pros and cons are discussed. Further the methods for FMI export and import in CATIA are explored with respect to implementing a co-simulation either in CATIA itself or other host programs. The two approaches are displayed by implementing simple examples. Ultimately possible applications for an advanced tool to link 3D geometric data and systems simulation, with the poten-tial to perform co-simulation, are presented.
