 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.# AVS field file
# this is a header file for a field to be
# used in conjunction with the  build a field module of AVS
#
ndim = 2
dim1 = 121
dim2 = 121
nspace = 2
veclen = 1
data = float
field = uniform
min_ext = -.762  -.762
max_ext =  .762   .762
label = normalized_RCS

variable 1 file=./almond.dat filetype=ascii skip=3

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