- Figure 1 – BlockM Interface
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.
The following documents contain the latest information regarding this interface (updated 09-Sept 2008): User_Guide.pdf, Examples.pdf
