What’s New in GetFEM 5.4

The main contribution of this version is a fully functional scripting language interface to Octave and support for definition and condensation of internal variables.

Released version, 2020/04/22.

The main changes are:

• A fully working Octave interface. Many thanks to Abderrahmane Bendali for the initial adaptation of this interface from Matlab’s one.

• Support for (internal) variables defined at integration points

• Full support for the automatic condensation of internal variables by local equations expressed in the generic weak form language. Useful for instance in the implementation of plasticity models.

• The use of Python 3 instead of Python 2.7 by default

• Support for Hybrid High-Order methods

• Support for the the assembly of product of terms defined on two different domains (integration on the product of two domains with a kernel, for instance).

• Support for Lumped Mass Matrix

• Support for Houbolt method
