flash.pyFlash4.Grid.Block

class Block(self: flash.pyFlash4.Grid.Block, blockID: int = 1, dataStruct: int = 2)

Bases: pybind11_object

Holds the grid data on a block for a single data structure either CENTER or FACE[XYZ].

Can be cast to a numpy array

myBlock = Block(blockID)
solnVec = np.array(myBlock, copy=False)

Using copy=False allows solnVec to use the same block pointer as myBlock.

the data may be accessed i.e.,

solnVec[var,i,j,k]

Parameters:

blockID (int) – local block id
dataStruct –
specifies the data structure (optional)

- The options are defined in constantsH and they are :

- CENTER cell centered variables (default)

- FACEX face centered variable on faces along IAXIS

- FACEY face centered variable on faces along JAXIS

- FACEZ face centered variable on faces along IAXIS

- SCRATCH scratch space that can fit cell and face centered variables

- SCRATCH_CTR scratch space for cell centered variables

- SCRATCH_FACEX scratch space facex variables

- SCRATCH_FACEY scratch space facey variables

- SCRATCH_FACEZ scratch space facez variables

__getitem__(self: flash.pyFlash4.Grid.Block, *args) → float

Access the grid data at (var,BC_DIR,SECOND_DIR,THIRD_DIR).

Parameters:

var (int) – 0-indexed grid variable, such as any of *_VAR from FlashH.
i (int) – 0-indexed to IAXIS in the region
j (int) – 0-indexed to JAXIS in the region
k (int) – 0-indexed to KAXIS in the region

__setitem__(self: flash.pyFlash4.Grid.Block, *args) → None

Assigns the grid data at (var,BC_DIR,SECOND_DIR,THIRD_DIR).

Parameters:

*args –
(var,i,j,k)
var (int) – 1-indexed grid variable, such as any of *_VAR from FlashH.
i (int) – 0-indexed to IAXIS in the region
j (int) – 0-indexed to JAXIS in the region
k (int) – 0-indexed to KAXIS in the region

property lo: array[3] holding the index of the first interior cell of the block
