Construct from the communicators and Eulerian information.
comm | is the communicator that contains the Eulerian and Lagrangian processors. | |
lagrangian | is the Lagrangian communicator. It is duplicated to avoid message conflicts. | |
eulerianSize | is the number of Eulerian processors. | |
eulerianRoot | is the rank of the Eulerian root in comm . | |
vertexIdentifierStyle | is either LocalIndices or GlobalIdentifiers. |

const void * | connectivities | |||
) |
Post sends for sending the local Lagrangian mesh to the relevant Eulerian processors.
numNodes | is the number of nodes in the mesh. | |
identifiers | are the global mesh node identifiers. | |
positions | are the meh node positions. This is an array of N-tuples of numbers. Each N-tuple is a Cartesian point. | |
velocities | are the mesh node velocities. | |
numFaces | is the number of faces in the mesh. | |
connectivities | describes the connectivites of the nodes to form faces. This is an array of N-tuples of integers. Each N-tuple represents on indexed face (line segment in 2-D, triangle in 3-D). If the vertex identifier style is LocalIndices , then each index is in the range [0..numFaces). If the style is GlobalIdentifers , then each element of connectivities is listed in the identifiers array. |
