Comparison of MATLAB Versions for CLI and GUI Performance
Although the MATLAB core language essentially has stayed the same throughout the years, the MATLAB runtime has with every release been extended with more functionality as well as featured significant improvements to the interpreter, Just-In-Time (JIT) compilation engine, and graphics capabilities. It is therefore easy …
CFD Solver Benchmark and Comparison - OpenFOAM, FEniCS and FEATool
Multi-Simulation and External Solvers in FEATool With the external solver and multi-simulation interfaces, FEATool Multiphysics makes it easy to use multiple solvers which can be suitable for different classes of problems. Using more than one solver can also be very helpful in validating physics models and simulations, …
Comparison of the DistMesh, Gmsh, and Triangle Mesh Generators
Having implemented and fully integrated a uniform MATLAB mesh generation framework with FEATool Multiphysics, it is now both very easy and convenient to directly compare mesh generation codes and algorithms with each other. In the following post the DistMesh, Gmsh, and Triangle open source mesh generators are compared …
Fortran, Julia, and MATLAB FEM Benchmark Comparison
Continuing the previous Finite Element Method (FEM) solver and assembly benchmark comparison, this follow up compares the entire solution process for an identical simulation problem, in this case a two-dimensional (2D) Poisson problem solved on a unit square. The model problem is stationary, and discretized with …
FEM Assembly and Solver Benchmarks
Although not very popular to undertake, and sometimes outright controversial, benchmarks and benchmarking is often very useful in order to be able to make fair and informed decisions about software codes, libraries, and choice of programming languages. With this in mind, several Finite Element Analysis (FEA) simulation …
Accurate Computational Fluid Dynamics CFD Simulations
In computational fluid dynamics (CFD) simulations accuracy is often very important, especially for drag and lift values. References [1-2] describe a CFD benchmark problem for time-dependent flow around a cylinder where the Reynolds number varies between 0<=Re<=100. The references contain very accuratly …
