Siemens PLM Software 5
• Automatic Resizing of Text Field in Predicate◦ Save time building queries
▪ Less clicks adjusting window size to enter text value◦ The text fields in predicates are now resized automatically as a function of the window size. Valid in:
▪ Query Editor▪ Repair Surface: Search Filters pane
• Search the Simulation Tree D4720◦ Get to the right object, faster
▪ Reduces time traversing the tree, reduces mouse clicks and mouse miles when searching for anobject
◦ The common keyboard shortcut for search, Ctrl+F, now opens a new Search panel next to thesimulation tree.
◦ In the Search box:1. Type the text to find.2. Within search results, which are presented either as a tree or a list view, highlight objects of interest.3. To locate and edit objects directly in the tree, right-click an object and choose Select in Application.
◦ ▪ Multiple search results of the same object type can be selected at once, and edited at once, withSelect in Application
Simcenter STAR-CCM+ 2019.1 | New features and enhancements
Siemens PLM Software 6
◦ The search experience is based on the filters framework:▪ The search pane has identical interaction modes as for filters both in the search results section and
in the advanced search section▪ The advanced search exposes the suite of predicates already available when building queries in
filters and query-based selections▪ A right-click in the advanced search mode allows you to save the search as a filter for later use
Simcenter STAR-CCM+ 2019.1 | New features and enhancements
Siemens PLM Software 7
◦ Additional considerations, related to the use of the search engine in the Filter framework:▪ The items that can be found by name search are named objects (for example: parts, regions,
reports, parameters, and other objects which you can rename) and the field functions (both systemand user field functions)- Objects that cannot be renamed cannot be found by name search (for example: Physics Models)
▪ Some objects that are not visible in the main tree may appear in search results. This is a knownlimitation. When using Select in Application on such search results, no object is selected in thetree
▪ Triggering the Search from any special mode, such as 3D-CAD or Surface Repair, searches thewhole simulation tree, and Select in Application takes you out of the tool and back into thesimulation tree, without closing the tool
