AddAllToVSPAEROControlSurfaceGroup()

void AddAllToVSPAEROControlSurfaceGroup

(

int

CSGroupIndex

)

Add all available control surfaces to the control surface group at the specified index

string wid = AddGeom( "WING", "" );                             // Add Wing

string aileron_id = AddSubSurf( wid, SS_CONTROL );                      // Add Control Surface Sub-Surface

int group_index = CreateVSPAEROControlSurfaceGroup(); // Empty control surface group

AddAllToVSPAEROControlSurfaceGroup( group_index );

Parameters

[in]

CSGroupIndex

Index of the control surface group

AddSelectedToCSGroup()

void AddSelectedToCSGroup	(	int@ []	selected,
		int	CSGroupIndex
	)

Add each control surfaces in the array of control surface indexes to the control surface group at the specified index.

Warning

The indexes in input "selected" must be matched with available control surfaces identified by GetAvailableCSNameVec. The "selected" input uses one- based indexing to associate available control surfaces.

string wid = AddGeom( "WING", "" ); // Add Wing

string aileron_id = AddSubSurf( wid, SS_CONTROL ); // Add Control Surface Sub-Surface

int group_index = CreateVSPAEROControlSurfaceGroup(); // Empty control surface group

array<string> @cs_name_vec = GetAvailableCSNameVec( group_index );

array < int > cs_ind_vec;

for ( int i = 0; i < cs_name_vec.size(); i++ )
{
    cs_ind_vec[i] = i + 1;
}

AddSelectedToCSGroup( cs_ind_vec, group_index ); // Add all available control surfaces to the group

Parameters

[in]	selected	Array of control surface indexes to add to the group. Note, the integer values are one based.
[in]	CSGroupIndex	Index of the control surface group

AutoGroupVSPAEROControlSurfaces()

void AutoGroupVSPAEROControlSurfaces

(

)

Creates the initial default grouping for the control surfaces. The initial grouping collects all surface copies of the sub-surface into a single group. For example if a wing is defined with an aileron and that wing is symmetrical about the xz plane there will be a surface copy of the master wing surface as well as a copy of the sub-surface. The two sub-surfaces may get deflected differently during analysis routines and can be identified uniquely by their full name.

string wid = AddGeom( "WING", "" );                             // Add Wing

string aileron_id = AddSubSurf( wid, SS_CONTROL );                      // Add Control Surface Sub-Surface

//==== Add Vertical tail and set some parameters =====//
string vert_id = AddGeom( "WING" );

SetGeomName( vert_id, "Vert" );

SetParmValUpdate( vert_id, "TotalArea", "WingGeom", 10.0 );
SetParmValUpdate( vert_id, "X_Rel_Location", "XForm", 8.5 );
SetParmValUpdate( vert_id, "X_Rel_Rotation", "XForm", 90 );

string rudder_id = AddSubSurf( vert_id, SS_CONTROL );                      // Add Control Surface Sub-Surface

AutoGroupVSPAEROControlSurfaces();





TEST_ASSERT( vsp::GetNumControlSurfaceGroups() == 3 );
vsp::Update();
TEST_ASSERT( !vsp::ErrorMgr.PopErrorAndPrint( stdout ) );
printf( "COMPLETE\n" );
string control_group_settings_container_id = vsp::FindContainer( "VSPAEROSettings", 0 );   // auto grouping produces parm containers within VSPAEROSettings

//==== Set Control Surface Group Deflection Angle ====//
printf( "\tSetting control surface group deflection angles..." );
TEST_ASSERT( !vsp::ErrorMgr.PopErrorAndPrint( stdout ) );
//  setup asymetric deflection for aileron
string deflection_gain_id;
// subsurfaces get added to groups with "CSGQualities_[geom_name]_[control_surf_name]"
// subsurfaces gain parm name is "Surf[surfndx]_Gain" starting from 0 to NumSymmetricCopies-1
deflection_gain_id = vsp::FindParm( control_group_settings_container_id, "Surf_" + aileron_id + "_0_Gain", "ControlSurfaceGroup_0" );
TEST_ASSERT_DELTA( vsp::SetParmValUpdate( deflection_gain_id, 0.8 ), 0.8, TEST_TOL );
deflection_gain_id = vsp::FindParm( control_group_settings_container_id, "Surf_" + aileron_id + "_1_Gain", "ControlSurfaceGroup_0" );
TEST_ASSERT_DELTA( vsp::SetParmValUpdate( deflection_gain_id, 1.2 ), 1.2, TEST_TOL );
//  deflect aileron
string deflection_angle_id = vsp::FindParm( control_group_settings_container_id, "DeflectionAngle", "ControlSurfaceGroup_0" );

CreateVSPAEROControlSurfaceGroup()

int CreateVSPAEROControlSurfaceGroup

(

)

Add a new VSPAERO control surface group using the default naming convention. The control surface group will not contain any control surfaces until they are added.

string wid = AddGeom( "WING", "" );                             // Add Wing

string aileron_id = AddSubSurf( wid, SS_CONTROL );                      // Add Control Surface Sub-Surface

int group_index = CreateVSPAEROControlSurfaceGroup(); // Empty control surface group

int num_group = GetNumControlSurfaceGroups();

if ( num_group != 1 ) { Print( "Error: CreateVSPAEROControlSurfaceGroup" ); }
