output field of files without header (sampling)
===============================================

This example doesn't do much, it just reads and makes a simple plot of OpenFoam
field in case of files without header (as for example the output of sampling
library)

.. GENERATED FROM PYTHON SOURCE LINES 11-15

Read a scalar sampled field and the associated mesh
---------------------------------------------------

.. note:: It reads a scalar sampled field and the associated mesh 

.. GENERATED FROM PYTHON SOURCE LINES 15-23

.. code-block:: Python


    # import readscalar, readvector function from fluidfoam package
    from fluidfoam import readscalar, readvector

    sol = '../output_samples/ascii/wohead'

    X, Y, Z = readvector(sol, 'faceCentres')
    pressure = readscalar(sol, 'p')

Now plot this scalar field
--------------------------
In this example it is the pressure coefficient around an airfoil.
It can be useful to sort the data in order to plot a line and not stars

    import matplotlib.pyplot as plt
    plt.figure()
    plt.plot(X, pressure, '*')
    plt.grid()
