Simple Layer

Concept

Class Layer is a successor of class Matrix, which is a collection of Block in a structure of 3D regular grid.

Class Layer removes Block from Matrix that do not have 0 coordinate by X or Y axes and applies transformations to remaining blocks Block that are connect their sides.

Filtered Matrix

Layer

We can change type of surfaces by X and Y axes to curved ones. Number of nodes by circumferential direction is determined by last number 0.5;;8 at first radial layer:

metadata:
  run:
    factory: geo
    strategy:
      class: strategy.NoBoolean
data:
  class: block.Layer
  layer: [ [ 0.5;;8, 1.5;;2 ],
           [ 1;;2, 2;;2, 3;;2 ] ]
  "layer_curves": [ [ line, circle_arc ],
                    [ line, line, line ] ]
  items_do_structure_map: 1
  items_do_quadrate_map: 1

Curved Layer

One can also change number of nodes by radial/height layer changing last number of subfields of first/second layer:

metadata:
  run:
    factory: geo
    strategy:
      class: strategy.NoBoolean
data:
  class: block.Layer
  layer: [ [ 0.5;;8, 1.5;;4 ],
           [ 1;;4, 2;;8, 3;;16 ] ]
  "layer_curves": [ [ line, circle_arc ],
                    [ line, line, line ] ]
  items_do_structure_map: 1
  items_do_quadrate_map: 1

Layer with different number of nodes by radial/height layers

Number of layers

One can add radial layers by appending additional items in the first layer subfield:

metadata:
run:
  factory: geo
  strategy:
    class: strategy.NoBoolean
data:
class: block.Layer
layer: [ [ 0.5;;8, 1.5;;2, 2.5;;2, 4;;2, 5;;2 ],
         [ 1;;2, 2;;2, 3;;2 ] ]
"layer_curves": [ [ line, circle_arc, line, circle_arc, line ],
                  [ line, line, line ] ]
items_do_structure_map: 1
items_do_quadrate_map: 1

Multi Layer

One can add height layers by appending additional items in the second layer subfield:

metadata:
run:
  factory: geo
  strategy:
    class: strategy.NoBoolean
data:
class: block.Layer
layer: [ [ 0.5;;8, 1.5;;2, 2.5;;2, 4;;2, 5;;2 ],
         [ 1;;2, 2;;2, 3;;2, 6;;2, 10;;2 ] ]
"layer_curves": [ [ line, circle_arc, line, circle_arc, line ],
                  [ line, line, line, line, line ] ]
items_do_structure_map: 1
items_do_quadrate_map: 1

Multi Height Layer

Zones

To specify zones one needs add items_zones and items_zones_map fields. Where items_zones is a list of pairs of volume and six surfaces names, e.g. [ Volume, [ NX, X, NY, Y, NZ, Z ] ]:

1. Volume - volume name

2. [ NX, X, NY, Y, NZ, Z ] - surfaces names:

   • NX - surface pointing in the opposite direction of X-axis

   • X - surface pointing in the direction of X-axis

   • NY - surface pointing in the opposite direction of Y-axis

   • Y - surface pointing in the direction of Y-axis

   • NZ - surface pointing in the opposite direction of Z-axis

   • Z - surface pointing in the direction of Z-axis

items_zones_map (and all fields that ends with _map) is an addressing array between items (Blocks in Layer) and corresponding index in some list with properties (e.g. items_zones) and has shape number-of-height by number-of-radial layers.

If one want to assign zone names with index 1 from items_zones ([ B, [ NX_B, X_B, NY_B, Y_B, NZ_B, Z_B ] ]) to 3th height layer and 5th radial layer one can set 1 to items_zones_map at [3, 5] location.

In this example we set:

1. 0 index of items_zones to middle (3th) height layer by all radial layers except last (5th);

2. 1 index of items_zones to 2nd and 4th height layer by all radial layers and also last (5th) radial layer in the middle (3th) height layer;

3. 2 index of items_zones to bottom (1st) and top (5th) height layer by all radial layers.

           [ 1;;2, 2;;2, 3;;2, 6;;2, 10;;2 ] ]
  "layer_curves": [ [ line, circle_arc, line, circle_arc, line ],
                    [ line, line, line, line, line ] ]

    [ 2, 2, 2, 2, 2],
