FEFLOW Newsletter April 2007

Dear FEFLOW user,

Many of you might already have seen the news on our website:

WASY is now a member of DHI Group.

The official announcement of the merger can be found below. Regardless of the changed ownership of our company, the WASY team will also in future be your primary contact for all questions concerning FEFLOW. In countries with a local DHI office, however, you may alternatively contact them in case you prefer a contact person speaking your language. FEFLOW will still be developed and furtherly improved by our experienced development team in Berlin, of course.

For FEFLOW 5.3, a new installation (FEFLOW 5.302) has been released. We recommend to download and install the patch as some bugs in the previous version have been fixed.

You would like a personal discussion with us or you are interested in who are the persons behind FEFLOW? Meet us at one of the scientific conferences where we exhibit our products!

Last, but not least: New FEFLOW training courses have been scheduled for the second half of the year.

For any questions, please do not hesitate to contact us, for example by email to support@wasy.de!

Kind regards,
The FEFLOW team
