_________________________________________________________________________________________________Next EPX Users' Meeting

The next « EPX Users’ Meeting » will be held on 13 June  2017.

This year, the Users’ Meeting will take place at the « EDF Lab Paris-Saclay » on EDF’s new Campus (Palaiseau, France), and we would like to thank our colleagues from EDF for this kind initiative.

As for the 1st edition, it will be a great opportunity to bring together EPX users and development teams. The meeting will be structured around presentations of recent developments and examples of EPX applications made by the users. We encourage you to present your work stemming from research projects, or industrial applications as these will contribute greatly to fruitful exchanges and will be a key to the success of the Users’ Meeting.

Please confirm your participation before 15 April 2017 and tell us if you intend to present your work.

From now on, the organization of the meeting is in the hands of our colleagues Patrick Vaugrante and Serguei Potapov from EDF who are your contacts for future exchanges about the Users’ Meeting. 

The EPX Team

 


 2017.0 EPX is out

The 2017.0 version of EPX is now available for both standard and parallel executions (OpenMPI, Intel_MPI).  See the release notes in the EPX docs section.

Linux x64 platform is currently supported. Windows x64  versions are now  released  (ER and Light versions). Mac OS.X versions are now dropped.

The 1.1.0 version of the EPXDATA module is still available and compatible with this version with no restriction.

 


New visual identity for EPX 

EPX now comes with a totally renewed visual identity, composed of a new logo available for download, to be inserted in communications involving the program, and a now color chart and page setup for the current website and the validation and release notes documents.

 


First EPX Users' Meeting

The first edition of EPX Users' Meeting held in CEA/Saclay on Thursday 2015, June 25th. It gathered around 40 people from 11 companies. The event was built around 8 technical presentations from developers, industrial users and academic researchers and 2 exchange sessions to deepen the bonds between the members of the EPX community.

This event is seen as a success by its participants and should be organized yearly from now, with a widened audience starting from next year.

 

Update - agenda, list of participants and slides available here.

 


Getting started with EPX

The slides and exercices from the course given at Universitat Politècnica de Catalunya, Barcelona in April, 2013 are now available in the EPX docs section.

They provide theoritical considerations on the algorithms implemented in the program and well-chosen datasets to start with EPX.

 


New Video Gallery 

 A video gallery is added to the What is EPX ? section.

  


EPX receives the French 2013 Grand Prix SFEN

On June 11th, 2013, the 'Grand Prix' of the French Nuclear Energy Society (SFEN) has been attributed to EPX, highlighting its major contribution over the last 30 years to the safety of nuclear reactors submitted to fast transient accidental situation, such as the Loss of Coolant Accident or the Core Disruptive Accident (see Grand Prix SFEN attributed to EPX).
