=========================================================
**CaseFOAM** - An OpenFOAM case manipulatior and creator.
=========================================================
.. _intro:
This module is a addition to ``PyFoam`` and can automatically setup OpenFOAM
cases with varying conditions.
.. _getting_started:
Getting started
===============
.. _installing-casefoam:
Installing CaseFOAM
-------------------
In order to use the Python module you need the ``PyFoam`` package.
install the package after cloning the repository with:
.. sourcecode:: bash
$ pip install .
or via pypi by executing:
.. sourcecode:: bash
$ pip install casefoam
User's Guide
------------
For a full documentation change into `doc` and build the documentation for
example as html.
.. sourcecode:: bash
$ cd doc/
$ make html
$ firefox build/html/index.html
Example
========
CaseFoam offers two main features: the easy generation of parameter studies
and the analysis of these. In the example, we want to change the intial height
of the column and perform a grid study for the damBreak test case:
.. image:: doc/media/damBreak.gif
parameter studies
-----------------
The first step is the generation of the cases. We want to generate three
column heights where each case has three grids with a differnt cell size.
.. sourcecode:: python
cat genCases.py:
import casefoam
baseCase = 'damBreak'
caseStructure = [['height_02', 'height_03', 'height_04'],
['grid1', 'grid2', 'grid3']
]
def update_grid(a,b,c,d,e):
return {
'system/blockMeshDict': {'#!stringManipulation': {'varA': '%s' %a,
'varB': '%s' %b,
'varC': '%s' %c,
'varD': '%s' %d,
'varE': '%s' %e
}
}
}
def update_height(height):
return {
'system/setFieldsDict': {'#!stringManipulation':
{'var_height': '%s' %height}}
}
caseData = {
'height_02': update_height(0.2),
'height_03': update_height(0.3),
'height_04': update_height(0.4),
'grid1': update_grid(23,8,19,42,4),
'grid2': update_grid(23*2,8*2,19*2,42*2,4*2),
'grid3': update_grid(23*3,8*3,19*3,42*3,4*3)
}
# generate cases
casefoam.mkCases(baseCase, caseStructure, caseData, hierarchy='tree',writeDir='Cases')
There a three different options how the cases can be manipulated:
- replacing a string inside the specified files
- executing a bash script
- by specifying a dictionary
for details please see the user manual.
The script is executed by:
.. sourcecode:: python
python genCases.py
This will the generate the following structure:
.. image:: doc/media/caseStructure.png
The cases can be started by running the newly created Allrun script
.. sourcecode:: python
./Allrun
postProcessing
--------------
Three functions are avaiable for the postProcessing:
- time_series
- positional_field
- posField_to_timeSeries
For the damBreak test case we want to plot the freesurface position at a given time.
For that, we use the positional_field function and get a pandas dataframe which we plot with holoviews
.. sourcecode:: python
import casefoam
import matplotlib.pyplot as plt
import pandas as pd
import holoviews as hv
hv.extension('bokeh')
caseStructure = [['height_02', 'height_03', 'height_04'],
['grid1', 'grid2', 'grid3']]
baseCase = 'Cases'
surfaceDir = 'freeSurface'
surface = casefoam.positional_field(surfaceDir,'U_freeSurface.raw',0.3,caseStructure,baseCase)
surface.columns = ['x','y','z','Ux','Uy','Uz','col_height','res']
surface_ds = hv.Dataset(surface, [ 'col_height','res'], ['x','y','z','Ux','Uy','Uz'])
holoviews is optimized for the use for the jupyter notebooks. The %%opts arguments are used to modify the layout of the plot.
holoviews renders an interactive plot which can be exported as html:
.. sourcecode:: python
%%opts Scatter [width=600,height=600,title='freeSurface at 0.3s',tools=['hover']]
%%opts (muted_alpha=0.0)
surface_ds.to(hv.Scatter,'x','y').overlay('res')
.. image:: doc/media/freeSurface.gif
