+ANSYScdb
+========
+
+Python module to extract data from ANSYS binary files and to display
+them if vtk is installed.  Currently only supports (*.rst) files.
+
+Installation
+------------
+
+From source directory
+
+``pip install .``
+
+or
+
+``python setup.py install``
+
+License
+-------
+
+ANSYScdb is licensed under the MIT license. The full statement is
+provided in the file named ``LICENSE``.
+
+Dependencies
+------------
+
+Required: ``numpy``, ``ANSYScdb``. Optional: ``vtk``
+
+Minimum requirements are numpy to extract results from a results file. To
+convert the raw data to a VTK unstructured grid, vtk 5.0 or greater must
+be installed with Python bindings.
+
+Tests
+-----
+
+Test installation with the following from Python
+
+.. code:: python
+
+    from pyansys import Tests
+
+    # Load a hexahedral beam modal analysis result file
+    Tests.Reader.Load()
+
+    # Display first bending mode of that beam
+    Tests.Reader.Display()
+
+
+Example Code
+------------
+
+Assumes you have the example files . Otherwise, replace
+‘Beam.cdb’ with your own blocked \*.cdb file.
+
+.. code:: python
+
+    # Load the reader from pyansys
+    from pyansys import Reader
+    
+    # Create result reader object
+    fobj = Reader.ResultReader('file.rst')
+    
+    # Get mode frequencies
+    freqs = fobj.tvalues
+    
+    # Get the node numbers in this result file
+    nnum = fobj.nnum
+    
+    # Get the mode shape at mode 7 (ANSYS result 7)
+    disp = fobj.GetResult(6) # uses 0 based indexing 
+    
+    # Load CDB (necessary for display)
+    fobj.LoadCDB('mesh.cdb')
+    
+    # Plot the displacement of Mode 41 in the x direction
+    fobj.PlotDisplacement(40, 'x')
+
