arb is described as 'Software package designed to solve arbitrary partial differential equations on unstructured meshes using an implicit finite volume method' and is an app. There are three alternatives to arb for Windows, Linux, Mac and MATLAB. The best arb alternative is FEATool Multiphysics, which is free. Other great apps like arb are COMSOL Multiphysics and COSMOSWorks.
FEATool Multiphysics is a fully integrated physics modeling and engineering simulation environment, featuring built-in CAD and geometry tools, pre-processing and grid generation, solvers, post-processing and visualization.
COMSOL Multiphysics is an engineering, design, and finite element analysis software environment for the modeling and simulation of any physics-based system.
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...
