The conservation of internal heat energy is given by

ρ c_p ( dT/dt+v[j]*grad(T)[j])-grad(\kappa grad(T)_{,i}=Q

n_i\kappa T_{,i}=0

it is assummed that ho c_p is constant in time.

solved by Taylor Galerkin method

Method Details

init(self, **kwargs)
(Constructor)

Creates a model.

Just calls the parent constructor.

Overrides: object.__init__: (inherited documentation)

doInitialization(self)

Initializes the time stepping scheme. This method is not called in case of a restart.

This function may be overwritten.

Overrides: escript.modelframe.Model.doInitialization: (inherited documentation)

doStepPostprocessing(self, dt)

perform taylor galerkin step

Overrides: escript.modelframe.Model.doStepPostprocessing

getSafeTimeStepSize(self, dt)

returns new step size

Overrides: escript.modelframe.Model.getSafeTimeStepSize
