Chimera Grid Tools: parameter size
 

I am trying to use the CGT with a database that contains a triangular mesh. When I use surgrd I get the message "Recompile using MEDGE > 102673". I have been looking everywhere in the source file but cannot find where the MEDGE parameter is set.

Does anybody know?

Thanks,
Claudio

Problem solved
 

Apparently a hard-to-find error in one of the input threw the CGT off. When I caught that the message of recompiling with a bigger size disappear. Still I wonder where MEDGE is set since I could not find it in any source or include files using "grep".

MEDGE is computed in the tridat.F subroutine (found in the lib subdirectory). The only way to make it larger, as far as I can tell, is to change the calculation from MEDGE=4*NVERT to something bigger. If you do that you will probably want to check the gui/og.c routine also - it appears that some storage is computed there which may need to be consistent with the tridat.F value. Beyond this, I cannot find any other places where MEDGE takes on a value. (This is for versions 1.7 and 1.8). Makes me wonder if the variable used to be a parameter when the check was first put in, but somewhere someone decided to compute it and never changed the check condition.
