build a one element mesh this is mostly useful for debugging Todo this doesn t get used much maybe remove it void apf changeMdsDimension Mesh2 in int d change the dimension of an MDS mesh this should be called before adding entities of dimension higher than the previous mesh dimension when building a higher dimensional mesh from a lower one or after removing all entities of higher dimension when reducing a high dimensional mesh to a lower one Field apf cloneField Field f Mesh onto Declare a copy of a field on another apf Mesh This will just make a Field object with the same properties but not fill in any data void apf construct Mesh2 m const int conn int nelem int etype GlobalToVert globalToVert construct a mesh from just a connectivity array this function is here to interface with very simple mesh formats Given a set of elements described only in terms of the ordered global ids of their vertices this function builds a reasonable apf Mesh2 structure and as a side effect returns a map from global ids to local vertices This is a fully scalable parallel mesh construction algorithm no processor incurs memory or runtime costs proportional to the global mesh size Note that all vertices will have zero coordinates so it is often good to use apf setCoords after this void apf convert Mesh in Mesh2 out convert one mesh data structure to another this function will fill in a structure that fully implements apf Mesh2 by using information from an implementation of apf Mesh This is a fully scalable parallel mesh conversion tool int apf countElementNodes FieldShape s int type count the

users should call the version which takes a MeshElement as input Only call this function if you know the other one isn t right for you Element apf createElement Field f MeshElement e Create a Field
