* createUniformGrid(dim, direction, pos, reflevel, quans, bbox) - Creates a uniform grid (class CUniformGrid) covering the AMR grid, with coordinates aligned with it, restricted with given arguments. Args: dim - dimension (1, 2 or 3); direction - normal to the plane (for 2d) or direction vector (for 1d); pos - position of the plane (2d, one coordinate) or the line segment (1d, two coma-separated coordines); reflevel - refinement level determining size of UG cells; quans - quantities to be stored in the UG, encapsulated in the CQuans object; bbox - bounding box, npa(dir,LO/HI).

|
|
* insRanges(axis, bounds, ncells) - Determines sets of indices in a block (bIdx) and in an axis (aIdx) for the situation when a block (defined with bounds and ncells) is inserted into a uniform grid (defined with axis). Args: axis - axis of a uniform grid; bounds - min & max of an inserted block along the given axis; ncells - number of cells of a block in a given direction. Ret: tuple of two npa - bIdx and aIdx.
|
|
|
|
* fillPlane(plane) - fills the plane (CUniformGrid) with he block data. At first it determines which blocks and quantities will be needed (separately for slices and integrals). Then, it reads them from file, transforms them to the same rlevel as the uniform grid, and inserts them there.

* ugAxis(direction, reflevel, bounds) - Creates an np array with grid cells coords along certain direction (0,1,2 = x, y, z), at a certain refinement level and restricted with bounds npa(2) - min, max).
