TOCHNOG is a free finite element program with many features. TOCHNOG
|
|
accepts free format input. Boundary conditions can be imposed at
|
|
geometrical entities, as well as nodes and elements.
|
|
|
|
Among the FE models supported are: differential equations (materials),
|
|
convection-diffusion equations, Stokes and Navier-Stokes (fluids),
|
|
elasticity (isotropy and transverse isotropy), plasticity (Von-Mises,
|
|
Mohr-Coulomb, etc.; plastic surfaces can be arbitrarily
|
|
combined). Residues in equations and error estimates for all data can
|
|
be printed or plotted using gnuplot/plotmtv
|
|
|
|
TOCHNOG supports a choice of description frames including Lagrangian,
|
|
Eulerian and arbitrary Eulerian-Lagrangian (AEL).
