Hi, I am currently working on a joint project between Tetra Pak Carton Ambient SpA and the University of Modena and Reggio Emilia (Italy), aimed to experiment with high-level, heterogeneous modelling in the field of automatic machines.
We were considering Ptolemy II as a possible simulation tool; however, for what concerns the physical part of the system, we would like to be able to write the model in a non-causal fashion (such as bond graphs) rather than using the block-diagram syntax that Ptolemy offers. As a result, we were wondering whether it could be possible to modify the program (more accurately, the CT domain) in order to allow the Director/Manager to: - Enforce a consistent connection between couples of connectors classified as a single Bond; - Perform an automatic causality assignment and change the internal structure of each Actor belonging to this new domain such that its input/output ports are connected according to the causality chosen. While the translation between block diagrams/causal bond graphs is always possible and causality assignment algorithms are more or less guaranteed to work under general conditions, I would greatly appreciate (and it could save me some time) the opinion of someone knowledgeable about the inner workings of Ptolemy. In particular, I am interested in assessments about the feasibility of such modifications and the amount of work necessary (the idea is to obtain a customization or an extension of the program, not to rewrite it from scratch: software development is not the primary objective of the project). Thanks in advance for your help, Luca Bassi ---------------------------------------------------------------------------- Posted to the ptolemy-hackers mailing list.
