Hi Rich,

Apologies - I sent you and email.

Thanks!

Re: Sign relation between damping rate and Imaginary frequency

Hi Rich, Yes, attached is one of my models and the gyre inlists for the adiabatic and non-adiabatic cases. I also attached a pdf of the normalized growth rates I'm getting, and the normalized Im(omega) values for the nonadiabatic diff_schemes. The line at -1.0 is the normalized Im(omega), just plott...

Re: Sign relation between damping rate and Imaginary frequency

Hi Rich, Thank you for the reply! I was indeed using MAGNUS_GL2. I tried COLLOC_GL4 and saw similar results. In trying the COLLOC_GL2 scheme, I got the same sign for the normalized growth rates and Im(omega) values for any given radial order, which appears more trustworthy. In viewing a prior post, ...

Inconsistent sign translation from normalized growth rate and Im(omega)

Hello, I was analyzing the normalized growth rates on a suite of 13 WD models. I'm particularly interested in the g-mode with radial order 2 (g2). For all 13 models, gyre reports a positive normalized growth rate. I verified this by numerically integrating the work integrals for the g2 mode for all ...

Re: Sign relation between damping rate and Imaginary frequency

Hello, I am having trouble with some inconsistency between the sign of Im(omega) and the growth rates gyre is reporting. I ran a suite of 13 WD models, and there is a spread in the sign of Im(omega) for a g-mode of radial order 2 (g2); some are positive and some are negative. However, the growth rat...
