The best free alternative to Simulink is Circuit JS, which is also Open Source. If that doesn't suit you, our users have ranked more than 25 alternatives to Simulink and many of them is free so hopefully you can find a suitable replacement. Other interesting free alternatives to Simulink are Xcos, SimulIDE, Ktechlab and OpenModelica.
Scicos is a graphical dynamical system modeler and simulator developed in the Metalau project at INRIA, Paris-Rocquencourt center. With Scicos, user can create block diagrams to model and simulate the dynamics of hybrid dynamical systems and compile models into executable code.
Kepler is a free open-source software system for designing, executing, reusing, evolving, archiving, and sharing scientific workflows. Kepler's facilities provide process and data monitoring, provenance information, and high-speed data movement.
Block model simulator for python BMS is a block model time simulator: it computes time values of time functions (called variables) linked by blocks which represent equations and behaviors between them.
Hopsan is an open-source multi-domain system simulation tool developed at the division of Fluid and Mechatronic Systems at Linköping University University.
Pictorus is a visual software development platform, designed from the ground up for modern engineers. Design and deploy powerful, reliable software from any browser to hardware instantly. Block diagrams are continuously re-compiled into binary executables for your target...
Caedium (formerly SymLab) and its add-ons combine to form an easy-to-use Computational Fluid Dynamics (CFD) software system to help you assess the performance of your 3D models.
Minsky enables the simulation of models (particularly from economics) defined in terms of coupled ordinary differential equations. The models are defined using a drawing canvas (rather like VisSim), and a double entry bookkeeping system known as a Godley table.
Altair Activate software is an open & flexible tool for rapidly modeling and simulating products as multi-disciplinary systems in the form of 1D models (expressed as signal-based or physical block diagrams), optionally coupled to 3D models.
Altair Activate is able to import .mdl and .slx files developed at simulink, this feature help to migrate from simulink to Activate. For now I believe this is the first software able to do that.
Is able to import simulink models
Explore powerful simulation algorithms for System Dynamics and Agent Based Modeling in a truly cohesive environment. Use System Dynamics to gain insights into your system. Use Agent Based Modeling to granularly break apart the details.
EMSO simulator is an equation-oriented process simulator with a graphical interface for modeling complex dynamic or steady-state processes. It is CAPE-OPEN compliant. EMSO stands for Environment for Modeling, Simulation, and Optimization.
Altair Embed™ software is a proven tool for developing embedded systems, by automatically generating code from block diagram models and transferring to popular controller hardware.
Aim of this project is bring classical control theory and signal processing to your projects. You can develop digital circuit in z-domain, simulate it and generate the portable c code. You can easily use it even on embedded projects because there is no single dependency, there...

I like Pictorus as an alternative to Simulink because it's easier to use, tightly integrates with my hardware, and is free for non-commercial users!
