models solversSet of different specialized solvers for different models
This module holds specialized solvers for different kind of applications and models.
This module holds the routine volume_michelsen which is a solver for
volume that takes advantage over a simple newton on the function of
pressure by solving the function of pressure over the covolume instead,
which solution is limited in the range [0, 1]. This solver requires that
the EoS uses the method get_v0 to return the covolume.
A basic code example
Volume solver at a given pressure.
