...Calculate and optimize the following: Minimum plate thickness (DNV/DNVGL-OS-C101) Minimum section modulus of stiffener/plate (DNVGL-OS-C101) Minimum shear area (DNVGL-OS-C101) Buckling (DNVGL-RP-C201) Fatigue for plate/stiffener connection (DNVGL-RP-C203) Compartments (tank pressures) are created automatically. Pressures on external hull (or any other generic location) is defined by specifying equations. You can optimize single plate/stiffener field or multiple.

...It plots stresses, deflections and the equilibrium path for imperfect circular cylinders showing the onset of yielding and limit points in relation to elastic and inelastic bifurcation buckling pressures. Two types of initial geometric imperfections, outer diameter out-of-roundness and outer-to-inner diameter eccentricity with a phase angle between them, can be considered. CPVparametric.xlsm, does parametric analyses. It plots performance parameters against depth or pressure for up to five different combinations of materials and shell geometries including initial imperfections. ...

...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.

...It also includes a range of features that facilitate the visualization and examination of various relevant quantities e.g. velocities, stress, rate of deformation, pressure, and finite strain. Folder contains a separate application, which illustrates analytical solutions of growth rate spectra for buckling and necking of a single viscous layer.
