[GiDlist] element numbering

[aliok at boun.edu.tr]

Hi,

I tried to download the beta version but I encountered a problem and I could
not succeed it. If it is possible, could you send me the version to my mail
adress
Thanks for your help

PS: Also I could not download the manuals in pdf format. Could you send them
either.




First, It's a illegal syntax to cross two loops or if - endif blocks
And you use some as:
*if(N0)
*format "%11i"
*LayerName
*loop elems *OnlyInLayer
*ElemsNum
*end if
*end elems

It's not valid to close the endif before to close the end elems

A valid sytax is:

*if(N0)
*format "%11i"
*LayerName
*loop elems *OnlyInLayer
*ElemsNum
*end elems
*end if

Other bug, you use *format "%11i" before to print *Layername, this format is
not valid for a string, you probably try
to print *ElemsNum with this integer format, must use this format order just
before *ElemenNum

Other efficiency detail: If you do not require to count the number or
elements of a layer,
and only need to know if has elements, instead
*set var N=0
*loop elems *OnlyInLayer
*if(ElemsLayerNum0)
*set var N=operation(N+1)
*end if
*end elems

Why check if ElemsLayerNum is 0 ?, and also, it,s much more efficient exit
the loop with break,
for example:

*set var N=0
*loop elems *OnlyInLayer
*set var N=1
*break
*end elems

About the last problem: are written all nodes for each layer, it's a GiD bug.
It not works correctly the modifier *onlyinlayer
for a loop nodes.
This bug is corrected for the next 7.4.5b beta version, but until this
version is available, can avoid this bug chequing
with a *if the node layer

*loop layers
*set Layer *LayerName *nodes
*LayerName
*loop nodes
*if(LayerNum==NodesLayerNum)
*format "%10i"
*NodesNum
*endif
*end nodes
*end layers

Note than instead *loop nodes *OnlyInLayer only is used *loop nodes , and is
added the *if(LayerNum==NodesLayerNum)

I attach the corrected *.bas compressed

Hi Enrique,

I tried to create element and node set by using layer utility.
I wrote follwing bas file to get sets.


ELEMENT SETS
*loop layers
*set Layer *LayerName *elems
*set var N=0
*loop elems *OnlyInLayer
*if(ElemsLayerNum0)
*set var N=operation(N+1)
*end if
*end elems
*if(N0)
*format "%11i"
*LayerName
*loop elems *OnlyInLayer
*ElemsNum
*end if
*end elems
*end layers
NODE SETS
*loop layers
*set Layer *LayerName *nodes
*format "%10i"
*LayerName
*loop nodes *OnlyInLayer
*NodesNum
*end nodes
*end layers

I encountered two problems. First one is that I could not get the triangle

element in the element sets. Secondly, although I set different nodes in
different subsets, it gives all nodes in the mesh generation for each
layer.

Thanks a lot.

Hi Enrique,

I want to set the one side of the element as a side set. I tried to do it
with layer option but it does not work. Is there any other ways to set a
element side in GID.

You probably need to define a condition "over face elements",
Read the online manual help about the conditions file
http://www.gidhome.com/support/gid_15.subst#SEC209

To use this information in the bas file, read the documentation about this
commands:
*set cond, *globalnodes. *localnodes
