Example 1: connect points in a 2d geometry
The objective is to connect a set of existing nodes (2 dimensional) into a triangle mesh that satisfies the Delaunay criterion using the connect command. The output consists of two gmv files - one showing the point distribution and the other showing the resulting triangle mesh.
Example:
# read the input points
read / avs / input.inp / cmopts
# create 2D mesh object and copy points
cmo/create/cmotri/ / /triplane
copypts/cmotri/ cmopts
cmo/delete/cmopts
# remove duplicate points if they exist
cmo/select/cmotri
filter/1,0,0
rmpoint/compress
# connect the points and set itp array
connect
resetpts/itp
# write AVS format file of the tri plane
dump / avs / output_2d_conn.inp / cmotri
# report mesh information
