KNDX simulation glitch #207

Uchiha-Itachi-San commented 1 year ago

There is a weird glitch happening with a simulation I an trying to run on Nakka-KNDX. The initial sim results are fine and show a burn time of around 3.56 sec. But as soon as I open the propellant editor the burn time shoots to 33 sec even if I don't make any changes. I have verified this on two different systems. I am using metric units for the simulation. If someone has faced a similar problem please let me know why this is happening and how to fix. Re-installing does not help.

That's not good! Could you post a screenshot of the burn rate graph for KNDX as shown in your propellant editor? Based on the discussion in https://github.com/reilleya/openMotor/issues/201 it seems like maybe the problem is something getting rounded down in a bad way when using metric units.
