Setup for 2D Cepheid models
- Rectangular computational domain:
small part of the stellar surface,
effects of surface curvature and variation of gravity ignored,
side length: 11x5.5 Gm, 5002 points (varying with Teff)
- Constant gravity: logg=2,
temperature sequence: 5000K < Teff < 6200K,
solar composition
- Lower boundary:
prescribed energy flux enters as radiation,
closed for matter
- Side boundaries:
periodic
- Top boundary:
Closed for matter, transmitting for radiation.
