Description of the Data

The module read_ucd imports data files in the following format:

<num of nodes> <num of cells> <data per node> <data per cell> <model data>
<nodeid> coordinates
<cellid> <cell shape> nodes
<data label> <data units>
<nodeid> data

An example of this is the hex.inp file which defines a single hexahedral cell with stress at each node:

8 1 1 0 0
   1  0.000   0.000   1.000
   2  1.000   0.000   1.000
   3  1.000   1.000   1.000
   4  0.000   1.000   1.000
   5  0.000   0.000   0.000
   6  1.000   0.000   0.000
   7  1.000   1.000   0.000
   8  0.000   1.000   0.000
   1  1 hex 1 2 3 4 5 6 7 8
   1 1
   stress, lb/in**2
   1  4999.9999  
   2  18749.9999 
   3  37500.0000
   4  56250.0000       
   5  74999.9999      
   6  93750.0001     
   7  107500.0003    
   8  5000.0001

Some of the other files containing sample UCD data can be found in /usr/avs/data/ucd:

• pyr.inp: example of a pyramid shaped cell
• tet.inp: example of a tetrahedral shaped cell
• bluntfin.inp: flow of air over a fin
• vec1.1000.inp: velocity at each node
• avs.inp: AVS logo
