TOCHNOG TOCHNOG is a free finite element program written in C++. Some program capabilities are: Input -- format free input, words and no magic numbers, boundary conditions at geometrical entities. output/plotting -- output at geometrical points, history of variables, interface to Gnuplot, Plotmtv, GMV or Tecplot (commercial) for plotting. elements -- 1D, 2D and 3D isoparametric elements, linear simplex elements, family of 1st to 4th order bar, quadrilateral and brick elements. mesh generation/refining -- macro regions are automatically divided into finite elements, local h-refinement, global h-refinement, global p-refinement, remeshing, mapping from old state variables. differential equations -- convection-diffusion equation -- temperature calculations. fluids -- Stokes and Navier-Stokes. solids -- elasticity (isotropy and transverse isotropy), plasticity (Von-Mises, Mohr-Coulomb, Gurson, etc.; plasticity surfaces can be arbitrarily combined), damage, hypoelasticity, viscoelasticity, viscoplasticity, viscosity. ground water flow equation -- Darcy law. wave equation. non-local calculations for softening materials -- a gradient model for plasticity, strain averaging within a radius for all material models. interaction analysis -- automatic fluid-solid interaction, temperature effects on fluids, solids. contact analysis -- with or without friction, frictional heat generation. frames of description -- Lagrangian, Eulerian, and AEL. type of analysis -- quasi-static and dynamic analysis. parallelization -- element nodal force calculation, contact algorithm, mapping of state variables when building a new mesh, determination of boundary conditions, nonlocal strain calculation, etc. TOCHNOG can utilize multiprocessor platforms with Linux kernels 2.0 or later and LinuxThreads.
