Dual cell or dual mesh method is used to __________(a) create boundary

1.	Dual cell or dual mesh method is used to __________(a) create boundary elements(b) create elements around a vertex(c) create cell-centred arrangement(d) create boundary facesThe question was asked at a job interview.The query is from Variable Arrangement in FVM topic in chapter Finite Volume Methods of Computational Fluid Dynamics
Answer» Correct CHOICE is (b) create elements AROUND a vertex The explanation is: In the vertex-centred arrangements, elements are created around the vertices by JOINING either their centroids or their centroids with the face-centroids. This method of forming the vertex-centred arrangement is called dual cell or dual mesh method.
