Lua

myWindsock Lua Simulation Script

A very powerful tool to customise your simulation. Write your own functions to modify the inputs into the simulation.

Example 1: simple kJ-limited boost 

                    -- Declaring Global energy budget (persists between steps)
                    kj = kj
                    or
                    25
                    -- Boost power while we still have kJ left and we're slower than the air (headwind)
                    if
                    speedMs
                    <
                    airSpeedMs
                    and
                    kj >
                    0
                    then
                    boost =
                    power
                    *
                    0.2
                    -- 20% boost
                    power
                    =
                    power
                    + boost
                    -- apply boost
                    boostKj = boost *
                    stepS
                    /
                    1000
                    -- convert W·s to kJ
                    kj = kj - boostKj
                    -- Deduct boost from Global energy budget
                    end

Example 2: overwrite simulation inputs 

                    -- Directly set CdA and massKg
                    cda
                    =
                    0.4
                    massKg
                    =
                    95

Mutable variables (Changeable)

  • power – rider power output (W)
  • cda – drag area (m²)
  • massKg – rider + bike mass (kg)
  • crr – coefficent of rolling resistance
  • drivetrainEfficiency – drivetrain efficiency (0 - 1)

Immutable (read-only)

  • elapsedS – seconds from start
  • stepS – step duration in seconds
  • distanceM – total distance in metres
  • altitudeM – altitude in metres
  • speedMs – speed in metres per second
  • airSpeedMs – air speed in metres per second
  • drivetrainEfficiency – drivetrain efficiency (0 - 1)
  • slope – gradient (0 - 1)
  • crr – rolling resistance coefficient
  • windBearing – wind direction in degrees
  • windSpeedMs – wind speed in metres per second
  • windSpeedShearedMs – sheared wind speed in metres per second
  • temperatureC – temperature in degrees Celsius
  • humidity – relative humidity (0 - 1)
  • travelBearing – travel direction in degrees
  • airDensity – air density in kg/m³

Tips

  • Use globals for memory, e.g. kj = kj or 25 .
  • Avoid infinite loops (like while true do ... end ) – they are blocked.
  • Keep logic light – your script runs thousands of times per ride.
