====== Running simulations ======

Simulations are run by pressing the {{:RunAll24.png|Run}} button on the [[Menu_bar#Toolbar|toolbar]] of the main window. The button does not activate until the model is free of errors (ref. [[Errors_window|errors window]]). The [[Simulations_window|simulations window]] will give simulation progress and report if errors occur during the simulation.

===== Simulation settings =====

Before running a simulation you should assign simulation settings. These include start- and end time, selection of simulation outputs and choice of [[Solver|Solver]]. Click the {{:SimulationSettings24.png|Simulation Settings}} button on the [[Menu_bar#Toolbar|toolbar]] to edit [[Simulation_settings|simulation settings]].

===== Simulation types =====

There are four available types of simulations in Ecolego. Before a simulation is started you must select which type of simulation you want to run from the [[Simulation_menu|simulation menu]].

  * **[[Deterministic_simulations|Deterministic]]** - A single iteration is run with best estimates for all parameter values. //(Default)//
  * **[[Probabilistic_analysis|Probabilistic]]** - Values for uncertain paremters are randomized using a Monte Carlo sampling method according to their probability density function. A large number of simulations are run. After the simulation is finished some [[Sensitivity_analysis|sensitivity analysis]] methods can be applied.
  * **[[Sensitivity_analysis|Sensitivity analysis]]** - Several methods exists for performing sensitivity analysis that are not based on random sampling, such as [[FAST|FAST]], [[Morris|Morris]] and [[Sobol|Sobol]]. This simulation run for many iterations, depending on the number of parameters that are included in the analysis and the method used. This simulation type is available only with the [[Sensitivity_analysis_toolbox|sensitivity analysis toolbox]].
