<div dir="ltr"><div>Hey MOAB-dev,<br><br></div><div>I have some quick questions about capabilities in MOAB:<br><br></div><div>1) For bridge_adjacencies, is it possible to have them return the original (calling) Entity as well? For example, if I call<br>
result = MeshTopoUtil(iface).get_bridge_adjacencies(*start_elem, 1, 2, NC);<br></div><div>on a 2D quadrilateral mesh where start_elem is a face, it will return the 4 adjacent cells (as intended). Is there an option to have it return start_elem AND the 4 adjacent cells?<br>
</div><div><br></div><div>2) Consider a variable length tag for a cell in a polyhedral mesh, with a tag length equal to the number of neighbouring cells. The neighbouring cells can be obtained with a bridge_adjacency. Is there a way to associate each entry of the tag with a specific cell from the bridge_adjacency in a consistent manner? This would be useful, for example, in generating/storing weights that are associated with a stencil.<br>
</div><div><br></div><div>3) For edges in a polyhedral mesh, my application requires the selection of a preferred direction (orientation) for flow across that edge. This is conventionally denoted n_{e,i}, where e is an edge and i is a cell; it is +1 for flow into the cell i and -1 for flow out of the cell i. What is the best way to represent this in MOAB? Is this connected to the side_number/canonical numbering?<br>
