Remeshing domain

Ver: 0
 

DESCRIPTION

For flow problems with free surfaces and/or mobile interfaces, a remeshing rule propagates the deformation of the boundary to the interior of the mesh.

Once a sub-task domain has a free surface or an interface as part of its boundary, remeshing is required on at least part of the sub-task domain.

Note that the remeshing rule never covers more than the sub-task domain; this guarantees the geometrical generality of the multifluid approach.

If the sub-task domain is composed of more than one subdomain, the remeshing rule can still be restricted to a part of the sub-task domain.

This allows the mesh to remain undeformed in regions where no remeshing is needed.

  OPTIONS
 
-2 
 Make the current domain empty
Cancels all previous sub-domain definitions.
In some situations, it is easier to build the domain of the current sub-task in "additive" rather than "substractive" mode.
-1 
  Upper level menu
0 
 Extension to the whole mesh
Complementary option to option -2
i 
 Removal of sub-domain i
Removes subdomain "i" from the current remeshing domain
j 
 Addition of sub-domain j
Adds subdomain "j" to the current remeshing domain
NOTES The free surface and/or moving interface must exist on the boundary of the remeshing domain.   SEE ALSO
