...The following failure modes are considered: • Shell stresses and displacements at mid-bay and ring-frames. • Axisymmetric collapse (AC). • Elastic and Inelastic Interbay Buckling. (EIB and IIB). • Elastic and Inelastic Monocoque Instability (EMI and IMI). • Ring-frame stress and Elastic Instability analysis (EFI). Solutions compare favorably with DTMB experimental results. DAPS4e.6’s IO is managed through a Visual Basic UserForm. Pre/post processing is done using macro-enabled Excel workbooks. ...

...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

A collection of Fortran 2003, 90 and 77 routines, modules and programs for automatic simulation based global constrained optimisation. The initial application is for FE simulation of elasto-plastic buckling of steel rods aimed at tuning the hardening model. Unix shell scripts are used extensively. High concurrency is achieved with parallel multi-start global search and with parallel MPI FE. Powell's BOBYQA or LINCOA are used (not included in this package). Automatic mesh generation of 3D cylinders is provided + automatic boundary conditions, all via Fortran and shell scripting.
