The parameters in this rollout control the size and resolution of the grid.
Cell size (MXS: cellsz) -
The size of one cell
X,Y,Z size (MXS: xc,
yc,
zc
) -
The grid size in cells
Boundary Condition
X,Y,Z (MXS: x_bound, y_bound, z_bound ) - select between different boundary conditions for the simulation grid.
Open - the simulation behaves as if there is infinite fluid beyond the boundary
Jammed(-) - the simulation behaves as if there is a solid boundary in the negative direction.
Jammed(+) - the simulation behaves as if there is a solid boundary in the positive direction.
Jammed Both - the simulation behaves as if there is a solid boundary in both directions.
Wrap - the left and right boundaries are connected(toroidal topology).
Adaptive (MXS: adaptive) -
Enables the adaptive grid mode and determines which channel will be kept inside (See Threshold parameter).
Threshold (MXS: grid_treshold) -
In adaptive mode the change of grid's size is performed when the content of a cell near to the borders crosses this value.
Limited by (MXS: limitby) - Determines whether the grid's expansion is to be limited. If that is the case, it also determines the units in which the Limited to value is expressed in.
None - No limitation.
Memory - Limit by the total consumed memory. The limit is specified in percents.
Cells - Limit by the cell count. The limit is specified in millions of cells.
Limited to (MXS: limit) - The limit of grid expansion (if active). The meaning of this value is given by the Limited by parameter.
No below initial grid (MXS: nbigrid) - when checked the initial grid is always inside of the adaptive grid.
Increase/Decrease resolution (MXS: ) -
Changes the resolution of the grid while maintaining its size.
