Well it has to fight it out with a large user base of Matlab and even in Europe againts the French INRIA's Scilab, Scicos and also with R, Octave and a real great experience in the user's interface without the hiccups of model incompatibilities between version like what 1.8.1 flags on Modelica 3.0 and Modelica 3.1 version calls? I can't figure out why it has no horizontal slider to move the image into the center even? This is my opinion of it. In ASIA its practically unheard off compared with the software I mentioned above - well call it straight talk but its true. Maybe the developers need to listen to real users?
