when I run the tcl file for 3d movement, the following error appears:

?Which OS are you using? Name and version, please.
( My test OS: No errors, the executable 'ns' is created OK.)

Testing : ns235-geo3D wireless3D.tcl : No errors

Your errors: Seems you are using a copy of ns (ns235-geo3D) with no "geo3D".
I.e. your error output is as the result from a stock ns-2.35 with no modifications.

You are supposed to unpack a new ns-allinone-2.35_gcc5.tar.gz
https://drive.google.com/file/d/0B7S...FDb7ul0VFk6FZQ
.... into a new directory, and start from scratch ...
You can have as many ns-allinone-2.xx as you want, at the same time

Example
/home/name/ns2/geo+olsr/ns-allinone-2.35
/home/name/ns2/geo/ns-allinone-2.35
/home/name/ns2/AA/ns-allinone-2.xx
.
/home/name/ns2/ZZ/ns-allinone-2.xx

it works for 3D movement thank you soo much.

My research is to improve the performance of the OLSR protocol using the ant algorithm.
I made the modification to the ant algorithm by entering the node velocity factor and the third dimension z.
How can I make these modifications to the OLSR protocol and its implementation?
can you help me please?

Re #16

`ns235-geo-olsr-64´ is a copy of my simulation example command.
I don't think you have this particular executable.
As with the previously discussed setdest3D/setdest3d, please use the command you actually have.

HOWTO
Type ns235-<TAB>
... to show your installed options (If any "ns235-...." command is available.)

When I modify the olsr code and execute the tcl file, the results remain the same as before.
Are there any instructions that I should implement after modifying the olsr code?
can you help me please.

Re #23

A modification may require three tings further to add :
1. "Tcl Hook" line(s) in the C++ code
2. Some lines in tcl/lib/ns-** files
3. New commands / lines in your simulation.tcl
