[Gmsh] node lists

[Bernhard Kubicek]

linux shell or cygwin is your friend:
replace "==102" with your "==yourZoneNr"

cat yourgmsh2asci.msh |grep -A 100000 "Elements" |awk '{if($4==102)
print $7 " " $8 " " $9" " $10" " $11" " $12" "$13 " " $14}' |sed
's/  //g'|sed 's/ /\n/g'|sort -nu 
Explenation:
grep to only have the lines after $Elements
awk searches for elements in the specified region, and outputs Node-Nr.
Blank Node-Nr. Blank Node-Nr. Blank for all existing and nonexisting
nodes, thereby usually creating Blank-Blanks.
Those are replaced by nothing in the next sed command.
Each remaining Blank is converted to a new line.
The list now is unordered and non-uniqe, which is resolved by sort.

very nice greetings,
 Bernhard
