Engineering tools already packaged in Debian
varkon A CAD-system with parametric modelling
pythoncad PythonCAD is a scriptable (with the Python language) and easy to use drafting program. Please note that this version still doesn't support DWG and DXF file formats.
sailcut A sail design and plotting software
Computer-aided manufacturing: use of computer software to control machine tools [...] in the manufacturing of workpieces (WP definition)
Partial Differential Equation (PDE) Solvers
Pre- and post-processing frameworks and tools
gmsh Gmsh is an automatic 3D finite element mesh generator (primarily Delaunay) with build-in CAD and post-processing facilities. Its design goal is to provide a simple meshing tool for academic test cases with parametric input and up to date visualization capabilities.
netgen Automatic 3d tetrahedral mesh generator.
gerris is a system for the solution of the partial differential equations describing fluid flow.
technog A free implicit/explicit finite element analysis program (Debian version is 20010124-3.2 at the time of writing)
Uncertainty treatment and quantification
Reliability analysis and sensitivity analysis for optimal design and control.
Numerical Computation (MATLAB/IDL like)
Engineering tools - Work in progress for inclusion in Debian
- Work in progress, waiting for the new upstream version
ufc ITP: 503072 (upstream) - UFC (Unified Form-assembly Code) is a unified framework for finite element assembly. More precisely, it defines a fixed interface for communicating low level routines (functions) for evaluating and assembling finite element variational forms.
pycam ITP: 600779 - toolpath generator for 3-axis CNC machining
