[esp-r] Re: topology tool and data

[Jon Hand]

There is a long term plan (or at least a wish or mine ) to have models which hold the
connection information only in the geometry files and which no longer need
the duplicate information in the *.cnn file (and the overhead).  

It will not be rocket science to do this (there are sufficient attributes in the
surfaces), just tedious and requiring some testing and some extra checks
in the code to ensure that changing names are dependency checked.  ;-)

The question I have also asked myself is: Is the .cnn file still necessary during calculation when using the new .geo format? If not, I think the original poster could edit the .geo file, only, during run-time (of a script, as I understand the intention). Or, the other way around, is editing of *only* the .cnn O.K. for bps?

run bps
change (.cnn or .geo)
run bps
... etc.

The functionality of the separate topology tool has been integrated into the ESP-r Project Manager
in browse edit simulate -> zone composition -> surface connections & boundary

It does the scan of all or part of the model and finds surfaces that are geometrically
associated as well as offering editing of individual connections.

Subject: [esp-r] topology tool and data

Dear all,

I am quite a beginner in esp-r and I am trying to evaluate whether it
can be valuable for my research. I posted a similar question on the
esp-r user club :
http://esp-r.forumactif.com/zones-geometry-topology-tool-f3/topology-tool-t74.htm

First, I am looking for the topology tool as a standalone in the
binaries (cfg as described here
http://www.esru.strath.ac.uk/Programs/ESP-r_tut/esp_aps.htm#ap_cfg). But
was not able to find it on the linux distribution. Is it still
available? Does compiling from source would make it appear ?? Can I
invoke it on the command line using prj?

Actually I would like to automate the creation of the connection list to
accommodate for parametrically changing topologies and thought that the
topology tool could achieve this from the zones geometry definition.
Does anyone has another (better) idea?

Also, looking closely at the files .cnn and .geo I realize that the
boundary conditi! ons is duplicated in the surfaces geometric definition.

..geo

*surf,part_a,VERT,-,-,-,int_part,OPAQUE,ANOTHER,01,01 # 6 ||<
part_a:reception

..cnn

2 6 3 1 1 # 18 part_a in examination >|< part_a in reception


Apparently, the .geo file is updated after running the topology tool.
However, when clearing the topology information, the .geo file is not
updated. Trying to save the (examination) zone geometry I get the following:

..geo

*surf,part_a,VERT,-,-,-,int_part,OPAQUE,ANOTHER,01,01 # 6 ||< external

..cnn

2 6 0 0 0 # 18 part_a in examination is External


When is the difference resolved?


Thanks in advance for the help.

Kind regards.
