New features in Version 2.9 of CalculiX (check the documentation!)
- For dynamic calculations several energy contributions are calculated and
printed to standard out.
- The stability of surface-to-surface penalty contact method and the speed of
both the node-to-surface and surface-to-surface penalty contact method were
- Several contact pairs can be defined underneath one and the same
*CONTACT PAIR card.
- Membranes and trusses were coded
- The meaning of the ERR error estimator was changed: now it is
the largest absolute and relative difference among the first (= largest in value) principal
stresses at the integration points in all elements belonging to one and the
same node. For HER the size of the heat flux vector is taking instead of
the first principal stress.
- The animation and sequence functionallity was improved.
- Previously only displacements could be animated by a sinus function
showing the deformed shape.
Now all kinds of datasets can be animated as a fringe plot with
- Fringe plots of sequences of datasets using the related deformed shapes
are also supported now.
This functionallities are available over the menu or the "ds" command.
- Deformed element- and model-edges are used during animations. The user
switch on additional undeformed edges as a reference over the "anim"
command or the "Animate" menu.
- Changed or extended commands:
- copy: More transformations are supported in case results have to be
copied as well (mir, rad).
- ds: The animation can now be used for fringe plots with or without
using the related deformations.
- max, A 3rd parameter "l" (lock) or "u" (unlock) can be provided
min, locks the scale to certain max or min values. The selection of
mm: a different dataset will not change the scale (max 100 e l).
- prnt: List the contents of the stack (prnt st)
- read: Results from "openFoam", stl-files and netgen meshes (.vol) can
be read now during run-time.
- send: Boundary conditions for the new ccx-cfd finite volume code
can be written with the 'slidef' parameter. These are equations
which define the velocity direction parallel to an element
- volu: The calculation of the element volumes was improved and is now
in accordance with the ccx solver since it uses the same
- New commands:
- anim: Command which provides the functionallity of the "Animate" menu
