A GTK+/Gnome2 graphical front end for the IW3HEV Vector Network Analyzer, also has a signal generator, and It displays graphicaly SWR, Phase, Return Loss, X impedance, Serial resistance, |Z| Impedanze, and Inductance, and capacitance.
An automatic 2D Delaunay mesh generator and solver for Finite Element Analysis. Can solve 2D field problems (Poisson and Helmholtz Equations). Can use LAPACK/ARPACK solvers producing OpenGL/Postscript output. Uses C/GTK/GTKGLExt/MFC. Runs on Win32/Unix.
