Add config variable for BKE turbulent conduction suppression

[wtbarnes]

See rice-solar-physics/HYDRAD#78

To me, it looks like there are four variables here that need to be added,

• USE_BKE -- boolean, whether to use this option
• BKE_L_T -- float,
• BKE_S_R -- float
• BKE_2L_R2 -- float

What specifically needs to be done to implement this? Add these to the template?

I'm willing to give it a shot.

So I think the first thing to work out is what are the variables that define the BKE conduction option? Are they the things I listed above? And then to work out which header file they go in. I'm assuming HYDRAD/source/config.h but perhaps that isn't correct.

Then it's just a matter of adding the logic to the template. If it is the HYDRAD config.h, it would be this one: https://github.com/rice-solar-physics/pydrad/blob/master/pydrad/configure/templates/hydrad.config.h. It could be something as simple as adding the following:

{% if general.bke %}
#define USE_BKE
#define BKE_L_T {{ general.bke.l_t }}
#define BKE_S_R {{ general.bke.s_r }}
#define BKE_2L_R2 {{ general.bke.2l_r2 }}
{% endif %}

This assume the existence of a bke entry in the config dictionary which is itself a dictionary with entries for l_t, s_r, and 2l_r2. It would be nice to also have more descriptive names for these variables and to document what they are.

l_t is the turbulence scale length. s_r is the center of the turbulent region. l_r is the Gaussian width of the turbulent region (centered at s_r) and so 2l_r2 is 2 x l_r^2 which is the quantity in the denominator of the exponential index used to calculate the distribution.Sent via the Samsung Galaxy S7 active, an AT&T 4G LTE smartphone -------- Original message --------From: Will Barnes notifications@github.com Date: 12/18/20 12:12 AM (GMT-06:00) To: rice-solar-physics/pydrad pydrad@noreply.github.com Cc: Subscribed subscribed@noreply.github.com Subject: Re: [rice-solar-physics/pydrad] Add config variable for BKE turbulent conduction suppression (#120) So I think the first thing to work out is what are the variables that define the BKE conduction option?
