Here is the call graph for this function:

Member Function Documentation

int TDomain::AdaptRefineAll ( )

Set Golbal Cell Number

PointNeighb's first column contains number of neib cells associated with each vertex

further columns contain the cell numbers associated with this vertex

POINT REFINEMENT AND LAYER REFINEMENT (FOR STRAIGHT LINE SHAPES)

Point Refinement START

vertex cell number

comment here if u dont want to run this routine

Point refinement END

Refinement Level 2 (OPTIONAL FOR POINT REFINEMENT)

Refinement Level 2 END

Refinement in layer for the 2D box Two Boundary Layer Problem

Type 1 (PRESENTLY WORKING): Using pointincell command to mark and refine initial cells containing the discontinuity

Type 1 END

Type 2 (PRESENTLY WORKING): Using product of normal and tangent vectors algorithm (but specific to this problem)

Type 2 End

This part below is written to prevent hanging nodes

Part 1: uncomment this part 1 and comment next part 2 to refine one layer up, i.e, after regular initial refinement again do regular refinement for the vertex neighbours and then do 1refine

Part 2:

END

edgewise refinement for layer start (Optional)

edgewise refinement for layer end

Type 3 (TO MODIFY): Generalized product of normal and tangent vector algorithm

Here is the call graph for this function:

void TDomain::CorrectParametersAndShapes ( )

set boundary parameters and cell shape according to possibly moving vertices

Here is the call graph for this function:

int TDomain::GenerateEdgeInfo ( )

generate edge info in 3D mesh

added by sashi

find max No. cells met any vertex in the collection

No. of edge neibs will not exceed MaxCpV

PointNeighb's first column contains number of neib cells met with each vertex

further columns contain the cell numbers met with this vertex

set the marker for Edges

set bound and isobound Edges

not modified if it is isobound edge

set all vertices on the bound face as bound vert

find No. cells having this edge

find the local index of the edge in all cells

generate the edge and set in all cells

Here is the call graph for this function:

TCollection * TDomain::GetCollection	(	TCollection *	coll,
		int	reference
	)

produce a collection with all cells of a given Collection which have the given reference as ReferenceID

This will give you a subcollection.

Here is the call graph for this function:

int TDomain::GmshGen ( char * GeoFile )

read Gmsh mesh

written by Sashi, 3D Gmsh

Here is the call graph for this function:

void TDomain::Init	(	char *	PRM,
		char *	GEO
	)

Init process for current domain.

initialize the grid, using the boundary parametrization in file PRM, and initial grid from file GEO, if GEO=="InitGrid" then the automatic mesh generator is used

Here is the call graph for this function:

void TDomain::MakeBdParamsConsistent ( TCollection * coll )

make boundary parameter consistent

Here is the call graph for this function:

int TDomain::MakeConfClosure ( )

refine the finest grid if necessary in order to get a grid with conforming closures

This function is used to set the right refinement descriptions to each cell such that the grid is conforming afterwards. After refinement of one ore more selected Cells this method has to be called.
