Description

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, CalculiX or gmsh.

TOCHNOG supports a choice of description frames including Lagrangian, Eulerian and arbitrary Eulerian-Lagrangian (AEL).

Install

As a binary package — by origin, or by package name:

pkg install cad/tochnog
pkg install tochnog

From the ports tree:

cd /usr/ports/cad/tochnog/ && make install clean

To depend on this port in another port's Makefile:

RUN_DEPENDS=	tochnog>0:cad/tochnog

Packages

The version each package repository carries. “-” means the repository builds no package of it, “n/a” that there is no such repository.
