VOLUME

Hi all,

I have a 3D domain, and I want to initialize the domain with different values. The “DOMAIN” will initialize uniform value for the whole system. So I need to define some VOLUMEs. If I have a cube, and the points are defined as follow:

#POINTS

0 0 0 0
1 1 0 0
2 0 1 0
3 0 0 1
4 0 1 1
5 1 0 1
6 1 1 0
7 1 1 1

How should I define the cube?

Thanks,

Xuan

There is no such functionality. You can consider the may of material group, e.g. assign the elements in the cube with an unique material ID when the mesh is generated.
Example: THM/thm_decov.ic

If you mean initial conditions, you can manually assign value to each node by using DIRECT as $DIS_TYPE in *.ic file as

$DIS_TYPE
  DIRECT
  ic.txt

The line after DIRECT indicates the name of a ASCII file which has two columns (node id, node value) separated by space or tab as

0 1.0
1 0.5
2 1.1
....

Nori

Thanks. Both methods work fine.
