ISI, developer of MATRIXx, had a MATRIXx product called Plug&Sim which allowed co-simulation with other simulation engines like ADAMS, EASY5 using CORBA through TCP/IP. This product was dropped during the transfer to The Mathworks. Is National Instruments planning on addressing the co-simulation and distributed simulation interests that drove this product developement? Would not the market for this product increase as time progresses and users require simulation of mechanical, electrical and other control systems? Could this be addressed through 3rd party or NI Alliance products?
