Global remeshing

Ver: 0
 

DESCRIPTION

For sub-tasks with free surfaces and/or moving interfaces, since a part of the boundary (free surface and/or moving interface) is deformed, either a part or the entire finite element mesh should also be deformed.

One or more local remeshing schemes can be defined on the deformed part of the mesh. The domains of the different local remeshing schemes do not overlap; the union of the local remeshing domains must totally incorporate the free surfaces and interfaces of the subtask.For sub-tasks with free surfaces and/or moving interfaces, since a part of the boundary (free surface and/or moving interface) is deformed, either a part or the entire finite element mesh should also be deformed.

  OPTIONS
 
-4' Enable line kinematic condition
Switches to line kinematic condition.
With line kinematic, 'Optimesh-3D' method is mandatory for any local remeshing.
This option is not available if a local remeshing does not use the 'Optimesh-3D' method.
-4" Disable line kinematic condition
Switches to surface kinematic condition
-3' Enable the inverse prediction
Allows the user to define an inverse problem. For use with extrusion-like flows.
-3" Disable the inverse prediction
Disable the capability of defining an inverse problem
-2 Deletion of a local remeshing
This deletes one remeshing previously defined
-1 Upper level menu
This goes back to the menu for the subtask
0 Creation of a local remeshing
This creates a new local remeshing scheme
i I-th local remeshing
This allows the user to enter or modify information about the i-th local remeshing scheme
NOTE Each local remehsing rule has its own remeshing type. Nodes located on the intersection between two remeshing rules move linearly. Locality of the remeshing is especially useful for non-simply connected domains.   EXAMPLES To create/modify the 1-st local remeshing scheme, select option 1 from the following menu:   Global remeshing
-4
 - Enable line kinematic condition (enter -4)
-3
 - Enable the inverse prediction (enter -3)
-2
 - Deletion of a local remeshing (enter -2)
-1
 - Upper level menu (enter -1 or CR)
0
 - Creation of a local remeshing (enter 0)
1
 - 1-st local remeshing (enter 1)

In the next menus, enter the desired information.
