No GSE glycol cooling on the pad

Seems like the recent changes in the GSE glycol cooling broke something. I don't have any cooling on the pad now, radiator and evap outlet temps go offscale high after the pump is switched on and remain high. Or do I have to change something in the .scn?

I am on build 1663 -that's why I'm asking.

Just try the standard "Apollo 11 Launch -MCC" scenario and power up the primary pump.
I know very well that all those system updates may invalidate my quicksaves, so I start from scratch from time to time. Yesterday it was time.;)

I will look into it, they were working fine for me after I pushed the fix but I will investigate!

Out of curiosity, what time acceleration do you use on the pad?

10x max. But even in 1x the rad out temp doesn't really go down to a comfy level. 70° F is the best I get. When I power up the IMU it gets even worse...

So its designed to be 60-70F right now. I am looking for better sources of GSE temps. What are you looking at for a "comfy level"?

I have made some tweaks to help cooling in time acceleration but I am trying to get a baseline of what you are seeing.

The AOH calls for 35 - 50° F, which does make sense. You've about 6 mins of flight with no heat sink in front of you. The system needs to be pre-chilled somehow.

Correct, the current heat exchangers were set for like 70. I have brought them down a lot in my testing branch and am working on a way to better "chill" it during time accel.

EDIT: Updating this, it turns out a recent radiator change is the culprit. We are investigating as to why and we should be able to fix it.

In the mean time, the code has been reverted and of course once you get in orbit things should behave :)
