Detailed Description

Defines the nodes and elements of a surface or volume mesh.

CMesh is a data structure that represents a mesh whith some additional functions to perform basic tasks and output to various file formats. As such, direct access to the data is provided. m_Nodes is a vector of nodes contained within the mesh. m_Indices is a list of indices into the nodes. The element types supported are listed in the ELEMENT_TYPE enum, this can be easily be extended. If this is done the GetNumNodes function must be updated to specify the number of nodes the element type uses.

Sample code to create a triangle mesh with two elements and save to STL is shown below: CMesh Mesh; Mesh.AddNode(XYZ(0,0,0)); Mesh.AddNode(XYZ(1,0,0)); Mesh.AddNode(XYZ(0,1,0)); Mesh.AddNode(XYZ(1,1,0)); vector<int> Tri1, Tri2; Tri1.push_back(0); Tri1.push_back(1); Tri1.push_back(2); Tri2.push_back(1); Tri2.push_back(3); Tri2.push_back(2); Mesh.AddElement(CMesh::TRI, Tri1); Mesh.AddElement(CMesh::TRI, Tri2); Mesh.SaveToSTL("sample.stl");

◆ CalculateVolume()

double CMesh::CalculateVolume ( ) const

Calculate the volume of the mesh.

If the mesh is a surface mesh, the surface must be completely closed and have triangle normals facing outside the volume. If the mesh contains quads, a copy of the mesh will be created and then the quads will be converted to triangles for volume calculation. Similarly if the mesh contains any 3d elements, these will be converted to 2d elements which will in turn be converted to triangles. The original mesh will not be affected.

This function is far more efficient than the function where the references are not given. References can be obtained with GetNodeElementReferences function which itself is rather time consuming. However GetNodeElementReferences need only be called once for multiple calls to ChangeNodeIndices. References will be updated reflecting the change in node indices.

		vector< pair< double, XYZ > > &	IntersectionPoints,
		pair< bool, bool >	TrimResults = `make_pair(false, false)`,
		bool	bForceFind = `false`
	)		const

Find the points where a line intersects the mesh.

Given a line defined by points P1 and P2, a list of intersection points Pi are calculated such that $P_i = P1 + (P2-P1) \mu_i$ . The values of $\mu_i$ are returned in IntersectionPoints along with the normal of the surface it intersects with. The list is sorted in ascending order of $\mu_i$ . This operation only works for triangular meshes! If you want to perform it for other mesh types it must be converted to triangles first using Convert3Dto2D and/or ConvertQuadstoTriangles.

Parameters

P1	Origin of the line
P2	End of the line
IntersectionPoints	Information about where the intersections occured
TrimResults	If true then only intersections found where $0 \le \mu_i \le 1$ are returned
bForceFind	Force the algorithm to find the closest intersection if no exact intersections can be found

Returns: Number of intersections found

◆ MeshConvexHull()

void CMesh::MeshConvexHull ( )

Create a triangular convex hull of the nodes contained within the mesh.

All elements will be removed before the hull is created. The incremental convex hull method is implemented, it is one of the simplest and more robust techniques however it can be slow for a large number of nodes. If this becomes a problem, an alternate method should be implemented. This function is only implemented for creating a convex hull of 3d points. A 2d equivalent should be fairly easy to implement, however is not necessary at this point.

	)

Save the mesh to ABAQUS input file format with information such as yarn tangents.

pElementInfo	Contains a vector of additional data attached to nodes or elements that should be saved (if specified additional .ori and .eld files will be generated)
bCreateStep	Create a step definition in the ABAQUS input deck, it may be desirable to ommit this and create step definitions manually, mainly because after a step definition is created any lines after this which affect the model definition are ignored.
bCreateMaterial	Create a material definition? Set this to false if you plan to create your own material definition.
iElementType	C3D8R if 0, C3D8 if 1
