FlexPDE is described as 'The Original Unlimited Scripted Multi-Physics Finite Element Solution Environment for Partial Differential Equations is now more powerful than ever!' and is an app. There are six alternatives to FlexPDE for a variety of platforms, including Windows, Linux, Mac, Web-based and Chrome OS apps. The best FlexPDE alternative is SymPy, which is both free and Open Source. Other great apps like FlexPDE are COMSOL Multiphysics, FEATool Multiphysics, OpenModelica and COSMOSWorks.
SymPy is a Python library for symbolic computation. The stated goals of the library are to become a full-featured computer algebra system and to keep a simple code base to promote extensibility and comprehensibility.
COMSOL Multiphysics is an engineering, design, and finite element analysis software environment for the modeling and simulation of any physics-based system.
FEATool is a fully integrated multiphysics modeling and engineering simulation environment for Matlab and Octave, featuring built-in CAD and geometry tools, preprocessing and grid generation, solvers, and postprocessing and visualization.
OpenModelica – A Free Modelica Environment! OpenModelica is an open-source Modelica-based modeling and simulation environment intended for industrial and academic usage. Its long-term development is supported by a non-profit organization – the Open Source Modelica Consortium (OS.
COSMOSWorks provides easy to use yet powerful design validation and optimization tools for designers and engineers alike. COSMOSWorks enables faster, less costly, and more optimized product development, as well as more in-depth examination of product performance than would ever...
StochSD (Stochastic System Dynamics) is a System Dynamics simulation software with focus on stochastics. It is a form of Continuous System Simulation (CSS) that in addition to model and simulate continuous flows between compartments, can handle transitions of discrete entities.
