Announcing trac@oofem

Every application has bugs – as long as humans write code. Every project needs the participation of its users to identify bugs, as well as to plan for new features.

We are happy to announce the availability of the bug tracking system, based on Trac project. All types of feedback – whether they're genuine bugs or feature requests – are to be reported using trac ticket system.

The oofem bugtracker is available at https://www.oofem.org/trac.

unv2oofem tool released

The new unv2oofem convertor translates unv-mesh (SRDC's I-DEAS) file format to native OOFEM input file. Unv file-type is an open ASCII datafile, which is used by several finite element codes. For example, this tool allows to use open-source SALOME pre-processor to prepare oofem model.

For more details, see description of Unv2oofem at oofem wiki.
