Element Numbering

Hi John,

There are no naming conventions - you can device any system you like! TOUGH2 does not care as long as element names are unique. The internal mesh generators (see block MESHM) employ some scheme to help identify rows and columns and layers, but it's difficult to describe this scheme in general as it has some "overflow" features that kick in depending on the number of elements in each direction (i.e., it is mesh-specific). But you can figure it out as the node center coordinates are also printed for each element.

I could give you simple Unix commands (e.g., sed) or editor instructions (e.g., in vi) to globally replace blanks/zeroes in element names (but I don't know whether you like Unix...). Alternatively, write your own little program in your favorite scripting/programming language to accomplish this. As an alternative to this alternative, go to SUBROUTINE OUT in file eosX.f and change the element names before you print them out.

Hope this helps,

Stefan

John,

Let me know exactly what you want (I did not understand "get rid of space, omit zeroes"). Assuming you want to replace a potential blank in the fourth slot of an element name by a zero, here is a simple command:

sed "s/^ \(...\) \(.\)  / \10\2  /" OUTFILE  | sed "s/^ \(..........\) \(.\)/ \10\2/" > OUTFILE_NO_BLANKS

This removes blanks in all elements and connection names in an output file, but is very basic and thus still ugly, as is throws some zeros in where they would not belong, but these extra can be removed equally easily if needed. I just want to give you the idea.

Cheers,

Stefan
