In your context 2.5 release should bring much benefit. regards raphaël [email protected] a écrit : Hi Martin we have fixed some performance issues in SysML. The modifications will be effective on Topcased 2.5. i hope they will help you :) Regards Tristan FAURE [email protected] a écrit : Dear Topcased Users, I'm currently working on a SysML model and a few days ago I had to include traceability links between this model and some requirements. The requirement were given in another SysML model, as <Requirement> elements. Therefore, I imported the requirement model into my functional model (using 'Load Resource') and start creating <Satisfy> elements to link these two models. Everything went fine ... until I closed my functional model for some reason and realize that I could not reopen it. The requirement model contains about 800 <Requirement> elements and 450 <Derive Reqt> elements, so it is reasonably big, but could be a lot bigger. What I find strange is that right after I imported my requirement model into the functional model, Topcased was still working fine and, although it did slow down a bit, it seemed to have enough memory to fit the 800 <Requirement> elements, so why isn't this the same when the model is loading ? Things got even stranger when I tried to load the requirement model into an empty model. The empty model that only imported one of the 800 <Requirement> still took 3mins to open ... but did open, while the functional model never could, even after waiting 30mins. After that I got curious and had a look at Windows' task manager. I realized that Topcased wasn't using the CPU at all and its memory consumption was holding at 280Mo. Yet, I didn't get any "out of memory" exception or any other exception ... I've already simplified the requirement model as best as I could with almost no effect. Could someone tell me if there is a way to load my requirement model and still be able to reopen my model without having to wait too much ? Is there some improvements planned for Topcased 2.5 that might help ?
