Starts a simulation of the nodes in the active model window, and writes the results to a file. A 窶彜ave as窶 dialog box appears where you can specify the name of the result file.
Note that only nodes with the 窶彜im.窶 attribute checked on will be stored on file. DynRisk will determine which parts of the model that need to be calculated in order to compute the simulation results for these nodes.
To check the 窶彜im.窶 attribute for a node, choose 窶彜imulation view窶 from the 窶廴odel窶 menu, and toggle this attribute on or off by clicking in the 窶彜im.窶 column in the table row of the node. The 窶彜im.窶 attribute is on if you see a 窶懌壺\ character in this field.
If the 窶廝ackground calculation窶 option is on, you may continue to work on other models while the simulation is performed. However, you cannot edit a model which is currently being simulated. The 窶廝ackground calculation窶 option is set using the 窶廴isc. options窶ｦ窶 command in the 窶弃reference窶 submenu of the 窶廡ile窶 menu.
If you are running a background simulation on the active model, the menu text will change to 窶彜top simulation窶. By choosing this command you may stop the ongoing simulation. Note however, that if you run the simulation as a foreground process, the simulation is terminated just by clicking the mouse button.
Test model
You may use this command to check the model before starting a simulation.
By default, the program includes the stochastic value in a test. By pressing the 窶彜hift窶 key while selecting this command, the program uses 窶彭eterministic values窶 of the nodes.
For a stochastic node this value is usually calculated as 窶廰ocal factor窶 * 窶廴id窶. However, if a node's distribution is 窶廝inary窶, the deterministic value is equal to the most likely value multiplied by the 窶廰ocal factor窶.
When you test a model, you can display 窶廬nput窶, 窶廰ocal窶 and 窶廾utput窶 values of nodes, and 窶廬nput窶 and 窶廾utput窶 values of edges.
Note that only nodes with the 窶彜im.窶 attribute checked on will be tested. DynRisk will determine which parts of the model that need to be calculated in order to compute the simulation results for these nodes.
Quicktest
Select a node or a group of nodes. Select 窶弉uicktest窶 and a dialog box appears. If you click on 窶彝andom窶, the program performs a calculation of the model including the stochastic properties. If you click on 窶廛eterministic窶, the program uses 窶彭eterministic values窶 of the nodes, as explained above.
