Condition on the direction of motion along boundary i

Ver: 0
 

DESCRIPTION

Allows the user to specify or to modify constraints applied on the direction of motion for free surfaces and interfaces.

By default, no constraints are imposed.

The current constraints are recalled in the header.

  OPTIONS

1 
 Modify the constraint on the X-component
Select this option if a constraint is imposed on the X-component
2 
 Modify the constraint on the Y-component
3 
 Modify the constraint on the Z-component
Available only in 3-D flows
NOTES The easiest way to constraint the motion of a free surface or of an interface in a direction is to impose a vanishing value for the corresponding component. This is useful to restrict the motion of free surfaces in planes of symmetry.   SEE ALSO
