rate

TransientReactiveTransport.rate(pores=[], throats=[], mode='group')

Calculates the net rate of material moving into a given set of pores or throats

Parameters:

• pores (array_like) – The pores for which the rate should be calculated

• throats (array_like) – The throats through which the rate should be calculated

• mode (str, optional) –

  Controls how to return the rate. The default value is ‘group’. Options are:

  mode	meaning
  ’group’	Returns the cumulative rate of material
  ’single’	Calculates the rate for each pore individually

Returns:

• If pores are specified, then the returned values indicate the

• net rate of material exiting the pore or pores. Thus a positive

• rate indicates material is leaving the pores, and negative values

• mean material is entering.

• If throats are specified the rate is calculated in the

• direction of the gradient, thus is always positive.

• If mode is ‘single’ then the cumulative rate through the given

• pores (or throats) are returned as a vector, if mode is

• ’group’ then the individual rates are summed and returned as a

• scalar.
