I made a quick lil config for people who use OPM along side the stock system

LAUNCHDESTINATIONS
{
	DESTINATION
	{
		ID = 0
		NAME = Low Kerbin Orbit
	}
	DESTINATION
	{
		ID = 1
		NAME = Keostationary Transfer
	}
	DESTINATION
	{
		ID = 2
		NAME = Munar Intercept
	}
	DESTINATION
	{
		ID = 3
		NAME = Minmus Intercept
	}
	DESTINATION
	{
		ID = 4
		NAME = Kerbin Escape
	}
	DESTINATION
	{
		ID = 5
		NAME = Eve Intercept
	}
	DESTINATION
	{
		ID = 6
		NAME = Duna Intercept
	}
	DESTINATION
	{
		ID = 7
		NAME = Dres Intercept
	}
	DESTINATION
	{
		ID = 8
		NAME = Moho Intercept
	}
	DESTINATION
	{
		ID = 9
		NAME = Jool Intercept
	}
	DESTINATION
	{
		ID = 10
		NAME = Sarnus Intercept
	}
	DESTINATION
	{
		ID = 11
		NAME = Urlum Intercept
	}
	DESTINATION
	{
		ID = 12
		NAME = Neidon Intercept
	}
	DESTINATION
	{
		ID = 13
		NAME = Plock Intercept
	}
}

Will the mod be updated further?

I'm still on the forums and I do intend to come back to this mod at some point, but have no time to work on it in the near future... 

If anybody wants to create a compatible release for more recent version of KSP they are very welcome to :)

This is traditionally done by linuxgurugamer.  If you write to him, I think there will be no problems.

Hi everyone,

I created a Octave script (should work on Matlab as well) which calculates payload capacities of a launch vehicle and shows results in a KLV config format (to avoid slowly increasing NRAP weight when doing it manually). Required inputs are dV of destinations in descending order and destination ID as defined in klvconfig.cfg (targetdV matrix), structural mass of the stages (m_s ), fuel mass of the stages (m_f) and specific impulse of stages (Isp)

 

clear all; close all; clc;
g_t = 9.81;
targetdV = [[9295; 15], [9055; 14], [8870; 13], [8785; 12], [8270; 11], [7595; 10], [7475; 9], [7135; 3], [6940; 8], [6920; 7], [6770; 5], [6745; 4], [6400; 2], [5400; 1], [5200; 0], [0.01; -1]];

% launch vehicle Ardea 3-1 20210227
m_s = [3.488, 7.323, 3.4]
m_f = [12, 23.255, 21.045]
Isp = [350, 320, 255.71]

nStages = length(m_s);
results = [];

j = 1;
maxdVset = false;

for i = 0:0.02:200
  m_initial = i;
  dV = 0;
  for x = 1:1:nStages
    m_empty = m_s(x) + m_initial;
    m_initial = m_empty + m_f(x);
    dVpartial = Isp(x) * g_t * log(m_initial / m_empty);
    dV = dV + dVpartial;
  end

  % find first suitable dV requirement
  if maxdVset == false
    destinations = length(targetdV);
    for l = 1:1:destinations
      if targetdV(1,l) <= dV
        j = l;
        break
      end
    end
    maxdVset = true;
  end
  % write last result if dV requirement is broken
  if dV <= targetdV(1,j)
    if i > 0.5
      results = [results,[targetdV(2,j);lastValue]];
    endif
    j = j + 1;
  else
    lastValue = i;
    lastdV = dV;
  end
end

formatSpec = '            LAUNCHCONFIG\n            {\n                DESTINATION = %d\n                PAYLOADMASS = %.3f \n            }\n';
fprintf(formatSpec,results)
