    Hi Taylor,

    Can you please say what could be causing the attached error?

    Thanks

    Hi Camella,

    LEAP uses a threshold to determine when its Transformation calculations have converged to the requirements for each module. This threshold is set in Basic Params: Calculations.

    For models with very small demands (i.e. 17.2 GJ), the software warns you that this is smaller than the convergence criterion. It can be interpreted in two ways:

    a) Your demand is unusually small (17.2 GJ is approximately the amount of energy required by 5 100 W light bulbs, operating continuously for a year), or

    b) You need to adjust the convergence criterion in Basic Params to make your model sensitive enough to your small demand.

    Best,

    Taylor
