 Activation de l'éclairage directX

  Reprise générale de la résolution éléments finis (statique et dynamique). Implémentation d'algorithmes plus rapides et performants : possibilité de calculer des structures de plusieurs milliers de noeuds. Utilisation de l'algorithme SSI ("Simultaneous Sliding Iteration") de PIPESTRESS pour l'extraction modale

 Nouvelle gestion dans le catalogue des profilés

  Possibilité de modéliser les sections non prismatiques (inertie variable).
Calculs exacts de la matrice de raideur et de la répartition des charges par intégration numérique.
Suppression de l'ancien système de modélisation de jarrets

  Possibilité de modéliser tout type de liaison entre les barres par génération automatique de ressorts. Voir nouveau catalogue des liaisons

 Calculs automatiques de la classe de section (Eurocode 3)

 Modification de la base de données, avec ajouts de la table "LIAISONS", et ajouts des colonnes "y0", "z0", "DIM_h2", "DIM_b2" et "FABRICATION" dans la table des sections

  Correction bug BS-65 (masses modales non prises en compte si affectées sur degrés de liberté bloqués et converties en charges nodales) .



November 2017 : New release PepS Version 6.1

Editpipe Version 9.1

Download Editpipe Enhancements pdf


 Changes in Editpipe Manager :

Warning and errors window: PIPESTRESS warnings can be classified in levels via a new configuration file easily editable.

The project management window and the merge restart window are now resizable.

Stress report generator: increased speed of generation.


 Changes in Editpipe :


Field TY for CROS cards is supported by the corresponding data list (only for values TY=0,1,2).

New options for deformed shape and arrows: can be rendered in foreground.

New option for jacketed pipe rendering: the outer pipe can be rendered either opaque or translucent or hidden.

New improved color map options to display stresses (including dithered stresses).

New data list "Stress On/Off".

New options for export to image: increase resolution and add a frame and a legend./p>

Tool to set the size of the piping view.

Improved filter: the filter can be modified from the data lists and the tree view.

Import/Export of STL files. Export your piping model to a STL file or visualize your STL file in Editpipe

Input File Edition

New custom editors for LCAS, CCAS and CSTR.

Smart edition or deletion: a tool to smartly edit or delete an element, a support or an analysis case.

Dynamic enumerations: list of possible values for fields that reference fields of other cards (e.g. field CD of a CROS card or field CA of an OPER card) is available in the generic card editor.

Hints and dynamic links: display valuable information about a field by moving the mouse over it while pressing the Ctrl key.

Auto completion: suggest field value when typing text inside the edit window.

Targeted version of PIPESTRESS. A new option that allows you to select the version of PIPESTRESS you plan to run for your calculations. Editpipe will adapt some functionalities to the chosen version, e.g. the manuals, the available fields for cards, the available code versions, etc. You can therefore enjoy the last version of Editpipe even if you must use an older version of PIPESTRESS.

 Interaction Between View and Input File

The undo and redo actions (Ctrl + Z / Ctrl + Shift + Z) are now enabled in the piping view window (the input file is modified and the view is updated).

A popup menu allows interaction with elements and supports in the view (edition, deletion, insertion, etc.).


Quick Analysis: a new tool to help you create analysis cards.

Improvement in the Quick Pipe wizard: possibility to activate hot modulus and hot allowable options, fill CD of CROS sections and reuse them, define a continuation line without a change in cross section, retrieve cross sections and materials from the xml library, etc.

Tree view: groups input data and display them in a tree. It can be used to interact with the input file or with the view.

XML library edition: a tool to edit the library without requiring knowledge of XML.
