 \caption{Model parameters for our different test models (A, B, C, and~D)
  and the hydrodynamic model (Hydro) compared to the values derived for
  WR~111 by \citep{gra1:02}.
 {\em Stellar core parameters}: 
 Stellar luminosity $L_\star$, radius $R_\star$,
 temperature $T_\star$, and mass $M_\star$
 (relevant only for the hydrodynamic model). 
 {\em Wind parameters}: 
 mass-loss rate $\dot{M}$ with the corresponding transformed radius $R_{\rm t}$,
 clumping factor $D$, and terminal wind velocity \vinf. 
 {\em Atmospheric abundances}: 
 mass fractions of helium, carbon, oxygen, silicon and iron
 $X_{\rm He}$, $X_{\rm C}$, $X_{\rm O}$, $X_{\rm Si}$, and $X_{\rm Fe}$.
 {\em Wind efficiency}: 
 resultant work-ratio $Q=W_{\rm wind}/L_{\rm wind}$
 according to Eqs.~(\ref{eq:wwind}) and (\ref{eq:lwind}),
 and wind momentum efficiency
 $\eta = L_\star / c\dot{M} \vinf$.\label{tab:parameters} }
