GiD forum

hello!
I am a Chinese student and often use GID. Now I use ver 6.1.2. I want to write a problemtype which can write a file to my calculating program,but I must use the layers. But I can't find the command about output how many layers,so I write a program with TCL which can output the number of layers. But now I meet a question: the number of layer outputting by my TCL program is a string,when I use this number in loop in *.bas,it do not work correctly.

Could you tell me who to tranform the string into a integer number?

My best wish to your!

yours,Niu

Download GiD 7.0-Beta2 (or 6.3.0b if you have a permanent password for GiD 6.x, the version 7.x requires a new password)
This version includes some layer commands inside the *.bas file whitout use tcl.

*LayerNum: returns the layer's number.
*LayerName: returns the layer's name.
*LayerName , *LayerNum must be inside a loop over layers; you cannot use this commands in a loop over nodes or elements.
*NodesLayerNum: returns the layer's number of a node. Must be used in a loop over nodes.
*NodesLayerName: returns the layer's name of a node. Must be used in a loop over nodes.
*ElemsLayerNum: returns the layer's number of a element. Must be used in a loop over elems.
*ElemsLayerName: returns the layer's name of a element. Must be used in a loop over elems.

Example 1:
*set Layer example_layer_1 *elems
*loop elems *OnlyInLayer
No:*ElemsNum Name of Layer:*ElemsLayerName No of Layer :*ElemsLayerNum
*end elems



Example 2:
*loop layers
*set Layer *LayerName *elems
*loop elems *OnlyInLayer
No:*ElemsNum Name of Layer:*ElemsLayerName No of Layer :*ElemsLayerNum
*end elems
*end layers

Example 3: count the number of layers
*set var NumberOfLayers=0
*loop layers
*set var=operation(NumberOfLayers+1)
*end layers
