Specific Desktop Tools: Main Tools


Wind Turbine InitialisationSet up a new wind turbine model, partly or completely based on the internal model

Functions ManagerDefine functions to be used for external load definition and for

definition of model properties

Load case Manager: Define Load Cases and Scenarios to be used in analysis

Refresh the 3D-viewerReload the graphics according to all modifications in the model and its parameters

S4WT Main Tools (1)

Main Tools: Functionalities






Import Object LibrariesImport external libraries of predefined / previously exported data for load cases and parameters into the session (these objects are called Engineering Objects as explained later)

Super Element ConversionConverts Ansys or Nastran super elements for inclusion into S4WT

Start an AnalysisStarts the simulation of selected analysis

S4WT Main Tools (2)Chapter 2: S4WT Desktop






Samcef Field Preprocessing: Displays selected component model in SField.

Samcef Field PostprocessingDisplay simulation results (animations, curves) and model in SFieldAnalysis/results to be displayed must be selected

2: Object Tree View

●

Browse for all objects within open S4WT session: hierarchical model components (SEAs, SEs), analyses/results, engineering objects (EOs), load cases, functions

●

Sort and filter by various criteria

Operations on Tree View

Filter tree view by:●

List:

all objects appear unsorted●

Model elements SE, SEA:

only model elements & analyses are displayed●

Analysis objects Analysis, Run:

All analyses and runs are displayed●

Data objects Load Case, EO:

Data objects are displayed, sorted by their types





Tree View: Operations


Operations on Tree View●

Filter tree view in addition by wildcard characters for object names

The filtered tree view is subjected to a secondary filter●

Select objects from tree view by wildcard characters

Characters are for instance “*”

and “?”●

Re-access defined filters●

Work with large data sets

e.g. with a high number of load cases and analyses
