Hi GiD team
Although I found a work around I love to know how I could (if possible) in
a .bas file
do the equivalent of files : import/export: write mesh

In this mesh file the number of the material written is the number of the
material in the .mat file ?

Regards
Mark

Found a solution, my mistake was misusing *ElemsMat
Solved the problem by changing my material file and the following in my bas
file

*loop materials
*set var MaterialNum(int)=Operation(MatProp(Number,int))
*loop elems
*ElemsNum 1 29650 *MaterialNum *ElemsConec
*end elems
*end materials

Dear GiD team,

I am having a problem writing out a mesh data file in my required format.
the following few lines from my .bas file are giving me problems:

*loop elems
*ElemsNum 1 29650 *ElemsMat *ElemsConec
*end elems


no mater what material I asign to my volume before meshing (linear tets),
the output file always shows the value 1 as the elements material.
If I do a write mesh then the output file shows the correct material number?
Whats going on?

Regards
Mark

Hello,

Can anyone give an estimate of memory requirement? For example, how much does
gid need to generate 0.5,1,5,10 million nodes respectively? How does memory grow
as number of nodes grows? I am using a unix system.

Yesterday, I was trying to generate about 6 million nodes mesh. It took couple
of hours to run and stopped suddenly with gid window closed. I think it was out
of memory. When I tried to restart gid, it began not to respond. Gid window
never showed up again even after I reinstalled it and ran gid.exe. I switched
from Gid6.1.3 to Gid7 and reinstalled it, the window still doesn't show up.Can
anyone help? What should I do?

Thanks,
Shuo Ma

In the bas file, the material number is not the same as defined in the .mat file, the materials are automatically
renumbered to avoid holes, from 1 to the number of really used materials.

If you desire to identify the material, you can use *Matprop(0) (inside a material loop) to obtain the material name.

*loop elems
*ElemsNum *ElemsMat *ElemsConec
*end elems

*loop materials
Number=*MatNum Name=*Matprop(0)
*end materials


You can also solve creating a field, named for example Number, for the materials, and storing the same value as the order in the mat file.
(this auxiliary field can be hidden.)

...
NUMBER: 5 MATERIAL: Steel_Top_Flange
QUESTION: NUMBER
VALUE: 5
STATE:HIDDEN
QUESTION: Elastic_modulus
VALUE: 20500
END MATERIAL
...

Your previous solution only work if only is assigned only one material to the model, inside each loop over materials are written all elements

instead:
*loop materials
*set var MaterialNum(int)=Operation(MatProp(Number,int))
*loop elems
*ElemsNum 1 29650 *MaterialNum *ElemsConec
*end elems
*end materials

use:
*loop materials
*loop elems
*if(MatNum==ElemsMat)
*ElemsNum 1 29650 *MatProp(Number,int) *ElemsConec
*end elems
*endif
*end materials

Hello,

Just as a example, we normally generate meshes of 3 Million tetra
elements
in a 1Gb RAM computer.
