Detailed Description

Function Documentation

ExportFile()

std::string vsp::ExportFile ( const std::string & file_name, int thick_set, int file_type, int subsFlag = 1, int thin_set = vsp::SET_NONE )

extern

Export a file from OpenVSP. Many formats are available, such as STL, IGES, and SVG. If a mesh is generated for a particular export, the ID of the MeshGeom will be returned. If no mesh is generated an empty string will be returned.

string wid = AddGeom( "WING" );             // Add Wing
 
ExportFile( "Airfoil_Metadata.csv", SET_ALL, EXPORT_SELIG_AIRFOIL );
 
string mesh_id = ExportFile( "Example_Mesh.msh", SET_ALL, EXPORT_GMSH );
DeleteGeom( mesh_id ); // Delete the mesh generated by the GMSH export

EXPORT_TYPE

Parameters

[in]	file_name	Export file name
[in]	thick_set	Set index to export (i.e. SET_ALL)
[in]	file_type	File type enum (i.e. EXPORT_IGES)
[in]	subsFlag	Flag to tag subsurfaces if MeshGeom is created
[in]	thin_set	Set index to export as degenerate geometry (i.e. SET_NONE)

Returns

Mesh Geom ID if the export generates a mesh

ImportFile()

std::string vsp::ImportFile ( const std::string & file_name, int file_type, const std::string & parent )

extern

Import a file into OpenVSP. Many formats are available, such as NASCART, V2, and BEM). The imported Geom, mesh, or other object is inserted as a child of the specified parent. If no parent or an invalid parent is given, the import will be done at the top level.

IMPORT_TYPE

Parameters

[in]	file_name	Import file name
[in]	file_type	File type enum (i.e. IMPORT_PTS)
[in]	parent	Parent Geom ID (ignored with empty string)

InsertVSPFile()

void vsp::InsertVSPFile ( const std::string & file_name, const std::string & parent_geom_id )

extern

Insert an external OpenVSP project into the current project. All Geoms in the external project are placed as children of the specified parent. If no parent or an invalid parent is given, the Geoms are inserted at the top level.

Parameters

[in]	file_name	string *.vsp3 filename
[in]	parent_geom_id	string Parent geom ID (ignored with empty string)

ReadVSPFile()

void vsp::ReadVSPFile ( const std::string & file_name )

extern

Load an OpenVSP project from a VSP3 file

string fid = AddGeom( "FUSELAGE", "" );             // Add Fuselage
 
string fname = "example_fuse.vsp3";
 
SetVSP3FileName( fname );
 
Update();
 
//==== Save Vehicle to File ====//
Print( "\tSaving vehicle file to: ", false );
 
Print( fname );
 
WriteVSPFile( GetVSPFileName(), SET_ALL );
 
//==== Reset Geometry ====//
Print( string( "--->Resetting VSP model to blank slate\n" ) );
 
ClearVSPModel();
 
ReadVSPFile( fname );

Parameters

[in]

file_name

*.vsp3 file name

SetBEMPropID()

void vsp::SetBEMPropID ( const string & prop_id )

extern

Set the ID of the propeller to be exported to a BEM file. Call this function before ExportFile.

//==== Add Prop Geometry ====//
string prop_id = AddGeom( "PROP" );
 
SetBEMPropID( prop_id );
 
ExportFile( "ExampleBEM.bem", SET_ALL, EXPORT_BEM );

See also

EXPORT_TYPE, ExportFile

Parameters

[in]

prop_id

Propeller Geom ID

SetVSP3FileName()

void vsp::SetVSP3FileName ( const std::string & file_name )

extern

Set the file name of a OpenVSP project

string fid = AddGeom( "FUSELAGE", "" );             // Add Fuselage
 
string fname = "example_fuse.vsp3";
 
SetVSP3FileName( fname );
 
Update();
 
//==== Save Vehicle to File ====//
Print( "\tSaving vehicle file to: ", false );
 
Print( fname );
 
WriteVSPFile( GetVSPFileName(), SET_ALL );
 
//==== Reset Geometry ====//
Print( string( "--->Resetting VSP model to blank slate\n" ) );
 
ClearVSPModel();
 
ReadVSPFile( fname );

Parameters

[in]

file_name

File name

WriteVSPFile()

void vsp::WriteVSPFile ( const std::string & file_name, int set = SET_ALL )

extern

Save the current OpenVSP project to a VSP3 file

string fid = AddGeom( "FUSELAGE", "" );             // Add Fuselage
 
string fname = "example_fuse.vsp3";
 
SetVSP3FileName( fname );
 
Update();
 
//==== Save Vehicle to File ====//
Print( "\tSaving vehicle file to: ", false );
 
Print( fname );
 
WriteVSPFile( GetVSPFileName(), SET_ALL );
 
//==== Reset Geometry ====//
Print( string( "--->Resetting VSP model to blank slate\n" ) );
 
ClearVSPModel();
 
ReadVSPFile( fname );

Parameters
