Scilab is becoming extremely popular among students of universities. It also has an alternative to MATLAB simulink which is called Xcos. Xcos is a simulation software for models of dynamic systems. You can also model control systems, signal processing systems, mathematical systems etc. Xcos has a large library of palettes which can be used for modelling and simulation of dynamic systems.
