Member Function Documentation

ErrorCode ReadRTT::build_moab	(	std::vector< node >	node_data,
		std::vector< facet >	facet_data,
		std::vector< tet >	tet_data,
		std::map< int, EntityHandle >	surface_map
	)		[private]

Builds the full MOAB representation of the data, making vertices from coordinates, triangles from vertices and tets from the same vertices. Tags appropriate to each dataset collection are applied, triangles are tagged with the surface id and side id they belong to, as well as tagging the surface with the same data. Tets are similarly tagged only with the Material number

Parameters:

node_data	the node data
facet_data,the	triangles in the problem
tet_data,the	tets in the problem
surface_map,the	map of surface meshset and id numbers

Returns:

moab::ErrorCode

Generate parent child links to create DAGMC like structure of surface meshsets being children of parent cell meshsets. By looping over the surfaces (1->N), look in the description of the cells that are shared by that surface, and then make the surface the child of the parent volume. The appropriate sense data will be set later

entity_map[4],vector	of maps containing data by dimension
side_data,vector	of all the side data in the problem

generates the topology of the problem from the already read input data, loops over the 2 and 3 dimension macrodata that exist from the rtt file, sides = dagmc surfaces, cells = dagmc cells, creates a meshset for each surface and tags with the id number, and similarly makes a meshset for dagmc cells and tags with the id number. The surfaces are added to the s surface map, where the key is the surface ID number (1->N) and (cells and surfaces are added to an dimesional entity map stored in the class

Parameters:

cell_data,vector	of vector of cell data
surface_map,reference	to the surface map of data
