Ple4Win 4.6.1 released

On February 12, 2020, a new version of the Ple4Win program has been released. This version is a service release, implying a larger number of smaller modifications, improvements and bug fixes but no truly new functionality. Nevertheless, this is a new version, not a patch, as existing functionality has been enhanced on several occasions.

For more information, see the newsletter about version 4.6.1. A detailed list of all bugs fixed, improvements and changes can be found here.

Best wishes for 2020

The device of the English artist (“Yes we can”)  is very appealing to us, civil engineers.

It seems impossible to observe buried objects (well), however, like the ostrich, having the largest eyes of all bird species and capable to see quickly and miles away, we bury our head in the sand for over over 50 years to analyse the behaviour of underground pipelines and advise on a good and safe design.

We wish you a successful 2020!

We are in the process of restoring both websites. While this is happening, some parts of the website such as the forum can be offline. Please be patient, we will restore functionality as soon as possible.

As the websites are hosted separately and no personal information is asked or stored (even the e-mail addresses for download are not retained) there has been no data breach, no personal identification information could have been obtained by the hackers.
