Homogeneous Models
Setting the model_type
parameter of the &model
namelist group to 'HOM'
tells the frontend to create a
homogeneous (uniform density) stellar model, equivalent to a
polytrope with index \(n=0\). Because the structure of these model
can be computed analytically, there is no need to read from an
external file.
The Gamma_1
parameter of the &model
namelist group
controls the first adiabatic index of the model, while the n
,
s
and grid_type
parameters control the model
grid. See the Stellar Model Parameters section for further details.
