Detailed Description

Function Documentation

AddCFDSource()

void vsp::AddCFDSource ( int type, const std::string & geom_id, int surf_index, double l1, double r1, double u1, double w1, double l2 = 0, double r2 = 0, double u2 = 0, double w2 = 0 )

extern

Add a CFD Mesh default source for the indicated Geom. Note, certain input params may not be used depending on the source type

//==== Add Pod Geom ====//
string pid = AddGeom( "POD", "" );
 
AddCFDSource( POINT_SOURCE, pid, 0, 0.25, 2.0, 0.5, 0.5 );      // Add A Point Source

CFD_MESH_SOURCE_TYPE

Parameters

[in]	type	CFD Mesh source type( i.e.BOX_SOURCE )
[in]	geom_id	string Geom ID
[in]	surf_index	Main surface index
[in]	l1	Source first edge length
[in]	r1	Source first radius
[in]	u1	Source first U location
[in]	w1	Source first W location
[in]	l2	Source second edge length
[in]	r2	Source second radius
[in]	u2	Source second U location
[in]	w2	Source second W location

AddDefaultSources()

void vsp::AddDefaultSources ( )

extern

Add default CFD Mesh sources for all Geoms

//==== Add Pod Geom ====//
string pid = AddGeom( "POD", "" );
 
AddDefaultSources(); // 3 Sources: Def_Fwd_PS, Def_Aft_PS, Def_Fwd_Aft_LS

ComputeCFDMesh()

void vsp::ComputeCFDMesh ( int set, int degenset, int file_export_types )

extern

Create a CFD Mesh for the components in the set. This analysis cannot be run through the Analysis Manager.

 //==== CFDMesh Method Facet Export =====//
 SetComputationFileName( CFD_FACET_TYPE, "TestCFDMeshFacet_API.facet" );
 
Print( "\tComputing CFDMesh..." );
 
 ComputeCFDMesh( SET_ALL, SET_NONE, CFD_FACET_TYPE );

COMPUTATION_FILE_TYPE

Parameters

[in]	set	int Set index (i.e. SET_ALL)
[in]	degenset	int DegenSet index (i.e. SET_NONE)
[in]	file_export_types	int CFD Mesh file type to export (supports XOR i.e CFD_SRF_TYPE & CFD_STL_TYPE)

DeleteAllCFDSources()

void vsp::DeleteAllCFDSources ( )

extern

Delete all CFD Mesh sources for all Geoms

//==== Add Pod Geom ====//
string pid = AddGeom( "POD", "" );
 
AddCFDSource( POINT_SOURCE, pid, 0, 0.25, 2.0, 0.5, 0.5 );      // Add A Point Source
 
DeleteAllCFDSources();

SetCFDMeshVal()

void vsp::SetCFDMeshVal ( int type, double val )

extern

Set the value of a specific CFD Mesh option

SetCFDMeshVal( CFD_MIN_EDGE_LEN, 1.0 );

See also

CFD_CONTROL_TYPE

Parameters

[in]	type	int CFD Mesh control type enum (i.e. CFD_GROWTH_RATIO)
[in]	val	double Value to set

SetCFDWakeFlag()

void vsp::SetCFDWakeFlag ( const std::string & geom_id, bool flag )

extern

Activate or deactivate the CFD Mesh wake for a particular Geom. Note, the wake flag is only applicable for wing-type surfaces. Also, this function is simply an alternative to setting the value of the Parm with the available Parm setting API functions.

//==== Add Wing Geom ====//
string wid = AddGeom( "WING", "" );
 
SetCFDWakeFlag( wid, true );
// This is equivalent to SetParmValUpdate( wid, "Wake", "Shape", 1.0 );
// To change the scale: SetParmValUpdate( wid, "WakeScale", "WakeSettings", 10.0 );
// To change the angle: SetParmValUpdate( wid, "WakeAngle", "WakeSettings", -5.0 );

See also

SetParmVal, SetParmValUpdate

Parameters

[in]	geom_id	string Geom ID
[in]	flag	True to activate, false to deactivate

SetComputationFileName()

void vsp::SetComputationFileName ( int file_type, const std::string & file_name )

extern

Get the file name of a specified file type. Note, this function cannot be used to set FEA Mesh file names.

//==== Set File Name ====//
SetComputationFileName( DEGEN_GEOM_CSV_TYPE, "TestDegenScript.csv" );
 
//==== Run Degen Geom ====//
ComputeDegenGeom( SET_ALL, DEGEN_GEOM_CSV_TYPE );

COMPUTATION_FILE_TYPE, SetFeaMeshFileName

Parameters

[in]	file_type	File type enum (i.e. CFD_TRI_TYPE, COMP_GEOM_TXT_TYPE)
[in]	file_name	File name
