20/*@C
21 DMSwarmSetPointsUniformCoordinates - Set point coordinates in a DMSwarm on a regular (ijk) grid
22
23 Collective on dm
24
25 Input parameters:
26+ dm - the DMSwarm
27. min - minimum coordinate values in the x, y, z directions (array of length dim)
28. max - maximum coordinate values in the x, y, z directions (array of length dim)
29. npoints - number of points in each spatial direction (array of length dim)
30- mode - indicates whether to append points to the swarm (ADD_VALUES), or over-ride existing points (INSERT_VALUES)
31
32 Level: beginner
33
34 Notes:
35 When using mode = INSERT_VALUES, this method will reset the number of particles in the DMSwarm
36 to be npoints[0]*npoints[1] (2D) or npoints[0]*npoints[1]*npoints[2] (3D). When using mode = ADD_VALUES,
37 new points will be appended to any already existing in the DMSwarm

457 DMSwarmProjectFields - Project a set of swarm fields onto the cell DM
458
459 Collective on dm
460
461 Input parameters:
462+ dm - the DMSwarm
463. nfields - the number of swarm fields to project
464. fieldnames - the textual names of the swarm fields to project
465. fields - an array of Vec's of length nfields
466- reuse - flag indicating whether the array and contents of fields should be re-used or internally allocated
467
468 Currently, the only available projection method consists of
469 phi_i = \sum_{p=0}^{np} N_i(x_p) phi_p dJ / \sum_{p=0}^{np} N_i(x_p) dJ
470 where phi_p is the swarm field at point p,
471 N_i() is the cell DM basis function at vertex i,
472 dJ is the determinant of the cell Jacobian and
473 phi_i is the projected vertex value of the field phi.
474
475 Level: beginner
476
477 Notes:
478
479 If reuse = PETSC_FALSE, this function will allocate the array of Vec's, and each individual Vec.
480 The user is responsible for destroying both the array and the individual Vec objects.
481
482 Only swarm fields registered with data type = PETSC_REAL can be projected onto the cell DM.
483
484 Only swarm fields of block size = 1 can currently be projected.
485
486 The only projection methods currently only support the DA (2D) and PLEX (triangles 2D).
