Detailed Description

Function Documentation

AddCFDSource()

void AddCFDSource	(	int	type,
		const string &in	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
	)

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 ====//
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	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 fisrt 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 AddDefaultSources

(

)

Add default CFD Mesh sources for all Geoms

//==== Add Pod Geom ====//
pid = AddGeom( "POD", "" );

AddDefaultSources(); // 3 Sources: Def_Fwd_PS, Def_Aft_PS, Def_Fwd_Aft_LS

ComputeCFDMesh()

void ComputeCFDMesh	(	int	set,
		int	file_type
	)

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, CFD_FACET_TYPE );

COMPUTATION_FILE_TYPE

Parameters

[in]	set	Set index (i.e. SET_ALL)
[in]	file_type	CFD Mesh file type to export (supports XOR i.e CFD_SRF_TYPE & CFD_STL_TYPE)

DeleteAllCFDSources()

void DeleteAllCFDSources

(

)

Delete all CFD Mesh sources for all Geoms

//==== Add Pod Geom ====//
pid = AddGeom( "POD", "" );

AddCFDSource( POINT_SOURCE, pid, 0, 0.25, 2.0, 0.5, 0.5 );      // Add A Point Source

DeleteAllCFDSources();

SetCFDMeshVal()

void SetCFDMeshVal	(	int	type,
		double	val
	)

Set the value of a specific CFD Mesh option

SetCFDMeshVal( CFD_MIN_EDGE_LEN, 1.0 );

See also

CFD_CONTROL_TYPE

Parameters

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

SetCFDWakeFlag()

void SetCFDWakeFlag	(	const string &in	geom_id,
		bool	flag
	)

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 ====//
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 );

SetParmVal, SetParmValUpdate

Parameters

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

SetComputationFileName()

void SetComputationFileName	(	int	file_type,
		const string &in	file_name
	)

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
