What’s New in GetFEM 5.3

The main contribution of this version is the extension of the language allowing macro definition and explicit differentiation.

Released version, 2018/06/22.

The main changes are:

• The weak form language now supports macro with parameters
• The weak form language has been extended with Grad(expression), the spatial gradient and Diff(expression, variable, direction) which performs a directional derivative. A few more tensor contraction operations has been added on this occasion.
• The support for pyramidal has been extended and stabilized.
• Incomplete pyramidal (13-node) and incomplete prism (15-node) elements have been added.
• Importing meshes from ANSYS has been improved/extended.
