Calibration with many sites to obtain best performance using a common set of parameters values for all sites

  • by pej
  • Posted on July 5, 2020
  • Bug Fixed

This procedure is based on using more than 2 dimension of a Multirun where the first dimension is used to specify the site specific parameters and the second is used to specify those parameters that […]

Deleted bug for solar angle and new error test

  • by pej
  • Posted on March 5, 2019
  • Bug Fixed

Simulations have not been perfectly stable and to some extent this is because of many new implementations of functions objects. To identify numerical problems with may be partly random a new error test have been […]

New options for Sensitivity Analysis – constrain by parameters

  • by pej
  • Posted on January 19, 2019
  • New Design of Simulations

MultiRuns with the CoupModel are mostly linked with some type of uncertainty based method to constrain the model outputs based on the agreement between one or more model outputs with corresponding measurements. This is done […]
