Product Overview

FEATFLOW
FEATFLOW

Description: FEATFLOW is an open-source simulation software for modeling incompressible fluid flow, heat and mass transfer, and fluid-structure interaction problems. It uses the finite element method and has interfaces for MATLAB and Paraview for preprocessing, solving, and postprocessing.

Type: software

Pricing: Open Source

ImplicitCAD
ImplicitCAD

Description: ImplicitCAD is an open-source computer-aided design (CAD) software focused on programmatic modeling for 3D printing. It allows users to describe 3D models parametrically using code rather than mouse clicks.

Type: software

Pricing: Open Source
