Hello,


accoring to the "Programmer's Guide", section "Blocking Commands", there are two alternative methods for the selection of nodes, faces or blocks: "all, or inpoly p1 p2 p3 p4, where each p is the xyz of a point". When I use "ic_hex_select_nodes 1 all m FLUID node_numbers" the program gives me a "Result: 21 37 25 41 22 38 26 42". But using "ic_hex_select_nodes 1 inpoly { 0.01 0.0 0.0 } { 0.01 0.005 0.0 } { 0.01 0.005 0.005 } { 0.01 0.0 0.005 } m FLUID node_numbers" results in "Usage: select_nodes max_nodes [i|j|k min max] [surface] [ text t1 t2 ... ] [ edge_nodes ] [ m m1 m2 m3 ... ] [ node_numbers ]". The Parameters here seem to be different to what is written in the "Programmer's Guide". Unfortunatelly I couldn't find any example for the usage of this option and no remarks on how the points p1..p4 have to be choosen or specified. Could anyone please give me an advise on how to use these commands?


Thanks in advance.

Hi flar.t

there is an old thread with the same problem: [problem] ICEM Scripting Loop to create points and Curves

There is an undocumented alternative mentioned to the stated list inpoly p1 p2 p3 p4.
You'll need to specify how many points and then sequentiall write the coordinates: #numberofpoints x1 y1 z1 x2 y2 z2 ...

The syntax looks like:

ic_hex_select_nodes 1 inpoly #numberofpoints x1 y1 z1 x2 y2 z2 .... m Parts node_numbers

And your example would probably read:

ic_hex_select_nodes 1 inpoly 4 0.01 0.0 0.0 0.01 0.005 0.0 0.01 0.005 0.005 0.01 0.0 0.005  m FLUID node_numbers

Best,

Hello Sebastian


thank you very much for your reply.

I saw that old thread before posting but unfortunately there is no explanation for the parameters at all. Now I understand how to use that option for the selection commands.



Best regards,
