...CalculiX is most popular FEA open-source package (like Code-Aster and Elmer-FEM). it is comparable in features with most known commercial packages like ANSYS, NASTRAN, Abaqus, etc. Good for structural, mechanical, thermal and fluid applications (trusses, plates, frames, shells, solid bodies). It has powerful nonlinear capabilities (including tension/compression only material like concrete) and most types of analysis (modal, thermal, buckling, coupled, etc) . See home page at http://www.dhondt.de New versions can be obtauned here: http://calculixforwin.blogspot.com/2015/05/calculix-launcher.html PS Appimages for Scilab, wxMaxima and GNU Octave were added

FRAME3DD is a program for the static and dynamic structural analysis of two- and three-dimensional frames and trusses with elastic and geometric stiffness.

Create Strain and Kinetic Energy Density maps out of a Natural Frequency extraction analysis (i.e. modal analysis). Works with a variety of FEA results format: NASTRAN, ABAQUS, Ansys, Medina/Permas.

ArchNURBS is a MATLAB tool for the analysis of planar curved structures, with a particular attention to masonry arches. As in CAD softwares, the geometry of the model is defined by a NURBS representation of the structure. Indeed, the user can upload geometries imported from a CAD environment. Based on such a representation, ArchNURBS performs the elastic isogeometric finite element analysis and the collapse limit analysis of the structure.

A solver based on the spectral element method, used in conjunction with FEMAP, as a pre- and post- processor. It solves the elastic wave propagation problem, and the coupling with a piezoelectric materials for excitation and sensing. It is currently in 2D and has both static and transient capabilities.
