Mesh Reconnection

Previous pageReturn to chapter overviewNext page

FlexPDE can automatically reconnect a moving mesh when the mesh becomes distorted or nonuniform. The reconnection option is turned on using the selector RECONNECT :

SELECT

RECONNECT(ON)        { turn on all reconnect operations }

 

There are three primary reconnection operations : PURGE (purging a node), SPLIT (splitting a nodal link by inserting a node), and SWAP (swapping a link between nodes) which can be controlled independently. E.g. :

SELECT

RECONNECT(purge,swap)        { turn on only the purge and swap operations }

 

These can be controlled globally in the SELECT section as well as regionally in the BOUNDARIES section.

REGION 1

RECONNECT(OFF)        { turn off all reconnect operations in this region }

 

REGION 2

RECONNECT(split)        { turn on only the split operation in this region }
