Parameters

General

The parameters in this rollout control the size and resolution of the grid.

Parameters

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 soli\d 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.

 

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.
