Read SDRC
				=========

There are two sample data files for use with the Read_SDRC
AVS module, called crankshaft.unv and trans-therm.unv.

Documentation for the module is included below, FYI.

DESCRIPTION

Read SDRC reads a file which is in the SDRC I-DEAS universal format
converts it into an AVS UCD format.

At present only two types of node data record are implemented, static
and transient.

  o  A static record has one set of values at each node.

  o  A transient record has a set of values at each node for different times. 
 
PARAMETERS

  Input File

    A file browser window to specify the name of the file to be read.

  Storage Option

    A set of radio buttons that display the present storage option.

      o  Store no node data records  - only structure data is held in the 
                                       output UCD structure.

      o  Store one node data record  - one node data record will be held 
                                       in the output UCD structure.

      o  Store all node data records - all node data records will be held 
                                       in the output UCD structure. 

  Store all transient data

    A boolean switch which only has effect on transient records. If set
    all transient steps of a transient data record are held in the output
    UCD, if not only one step is held.

  Active node

    A set of radio buttons displaying the set of node data records in
    the current file.  When one is chosen it is loaded and set active
    in the output UCD structure.

  Set data range

    A boolean switch which if it is set then the min and max val float
    parameters are used as limits to the current active node data. If
    not then the minimum and maximum values in the actual dataset are used.
    Note that this can only be used on scalar data sets and care should 
    be taken as no checking is performed to see if the extents chosen
    relate to the actual data values.

  Time step

    A time dial which is used for transient records. The nearest time
   dataset to the value on the dial is loaded and set active in the
   output UCD structure.

  Forward step

    A oneshot which loads and sets active the next transient dataset
    in the output UCD structure.
      
OUTPUTS

  UCD Structure

    The output structure is an AVS Unstructured Cell Data (UCD) format.

  Choice

    The output is the currently active dataset choice which is
    the one that should be used for further computation.

  
EXAMPLE

1. The following network reads an SDRC file and colours the surface according
   to one of the scalar datasets.

2. The following network reads an SDRC file and colours the surface according
   to one of the scalar datasets which has been extracted using the
   UCD EXTRACT module.

     GENERATE COLORMAP	       READ SDRC

	      |	     |------------|
              |      |
