Block Mesh
Purpose:
This interface is for index based mesh generation and is similar to mesh generation methods used in LS-INGRID. This capability is under development and eventually will be expanded to be a very powerful addition to LS-PrePost.
Function:
Create : Create blocks.
Parameter : Parameter and Expression.
Bland/Del : Blank or delete blocks.
Rd/Write : Read and write command files.
Move Pts. : Move points.
Distribute : Distribute blocks' nodes.
Rotate Pts : Rotate points.
Project : Project points/lines/surfaces of blocks to geoemtry.
Info : Show internal node coordinate of given block.
Sample:
no sample.

Multiple Blocks : Create multi blocks.
Single Block : Create single blocks.
Butterfly Block : Create a butterfly block.
