UniformRefinement()

void TPZGenSpecialGrid::UniformRefinement ( const int  nUniformRefs, TPZGeoMesh *  gmesh, const int  dimelfordivision, bool  allmaterial = true, const int  matidtodivided = 0  )

static

Make uniform refinement of the geometric mesh. This method finishs making the new connectivities for the elements (ResetConnectivities() and BuildConnectivity())

Parameters

nUniformRefs	Number of divisions of all elements wished
gmesh	Geometric mesh contained the elements
dimelfordivision	Dimension of the geometric elements will be divided. If dimelfordivision is negative subdivide all elements (for any dimensions)
allmaterial	If true divides all geometric element, if false check the material match with allmaterial to divide the element
matidtodivided	To divide only elements with this material id

Make uniform refinement of the geometric mesh. This method finishs making the new connectivities for the elements (ResetConnectivities() and BuildConnectivity())
