===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 
[[http://trac.edgewall.org/|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 [[http://www.oofem.org/wiki/doku.php?id=unv2oofem:unv2oofem|Unv2oofem at oofem wiki]].
