TOCHNOG\naccepts free format input. Boundary conditions can be imposed at\ngeometrical entities, as well as nodes and elements.\n\nAmong the FE models supported are: differential equations (materials),\nconvection-diffusion equations, Stokes and Navier-Stokes (fluids),\nelasticity (isotropy and transverse isotropy), plasticity (Von-Mises,\nMohr-Coulomb, etc.; plastic surfaces can be arbitrarily\ncombined). Residues in equations and error estimates for all data can\nbe printed or plotted using gnuplot/plotmtv, CalculiX or gmsh.\n\nTOCHNOG supports a choice of description frames including Lagrangian,\nEulerian and arbitrary Eulerian-Lagrangian (AEL).","flavors":[],"html":"https://daemonports.org/dragonfly/cad/tochnog/","kind":"port","lastUpdate":null,"license":["GPLv2"],"maintainer":"ports@FreeBSD.org","name":"tochnog","newest":true,"newestVersion":"20140100","noVulnData":false,"origin":"cad/tochnog","otherSystems":[{"maintainer":"ports@FreeBSD.org","newest":true,"origin":"cad/tochnog","path":"/cad/tochnog/","system":"FreeBSD","updated":"2026-07-14","version":"20140100_15"},{"maintainer":"pkgsrc-users@NetBSD.org","matchedBy":"name","origin":"math/tochnog","path":"/netbsd/math/tochnog/","system":"NetBSD","version":"20010429"},{"maintainer":"ports@MidnightBSD.org","newest":true,"noVulnData":true,"origin":"cad/tochnog","path":"/midnightbsd/cad/tochnog/","system":"MidnightBSD","version":"20140100"},{"maintainer":"ports@FreeBSD.org","newest":true,"noVulnData":true,"origin":"cad/tochnog","path":"","system":"HardenedBSD","version":"20140100_15"},{"maintainer":"ports@FreeBSD.org","newest":true,"noVulnData":true,"origin":"cad/tochnog","path":"","system":"GhostBSD","version":"20140100_15"}],"packages":null,"pkgName":"tochnog-20140100_13","related":null,"repository":"DPorts","requiredBy":[],"requiredByCount":0,"runDepends":["lang/gcc11","math/blas","math/lapack","math/superlu"],"status":null,"system":"dragonfly","systemLabel":"DragonFly","version":"20140100_13","versions":null,"vulnerabilities":null,"www":"https://tochnog.sourceforge.net/"}
