- Hi, I am new to this group and AVS. I need some advise on the simple
- problem below.
-
- I am having trouble passing parameters "min_ext" and "max_ext"
- from module "read field" to "field to mesh" in the network below
-
-
- |Read Field|
- |
- |
- |
- |Field to Mesh| |Generate Axes|
- | |
- |------------------------

- |Geometry Viewer|
-
-
- What I was trying to do is to display 2d uniform field
- between min_ext and max_ext (both x and y) so that I can superimpose
- another geometry on top later on.
-
- What I got was a mesh spaced between 0 and 120 instead of
- between min_ext and max_ext in both x and y directions.
- So, the question is how to display the mesh correctly between
- the min and max specified.
-
- I prefer not having to generate the xy coordinate points for
- each grid point, the field is uniformly spaced. And module
- "volume bounds" is not compatible with the 2d field.
-
- Thank you very much for responding. Please response via email.
- I use AVS Release 4 on a Sun if it matters.

- PS: Below is the field file to read the data.

- # this is a header file for a field to be
