Adding generators example

This example PyTOUGH script opens a geometry file and TOUGH2 data file and assigns uniformly distributed heat generators over a circular region of the basement of the model (within a specified radius of the centre of the upflow).

geo = mulgrid('gmodel.dat')
dat = t2data('model.dat')

upflow_centre = np.array([15000., 21000.])
upflow_radius = 1200.
totalheat = 10.e6

layer = geo.layerlist[-1]  # bottom layer
cols = [col for col in geo.columnlist if 
        np.linalg.norm(col.centre - upflow_centre) <= upflow_radius]
totalarea = sum([col.area for col in cols])
q = totalheat / totalarea

dat.clear_generators()
for col in cols:
    blockname = geo.block_name(layer.name, col.name)
    gen = t2generator(name = ' q' + col.name, block = blockname,
                      type = 'HEAT', gx = q * col.area)
    dat.add_generator(gen)

dat.write()

Here the numpy function linalg.norm is used to calculate the distance between each column centre and the centre of the upflow, to see if it lies within the upflow region.
