RunDynam. Working with Several Different Simulations in the Same Directory?

In this FAQ page, we address several related questions which users of RunDynam (RunMONASH, RunGDyn etc) may be unsure about.

Question 1. How can I set up and run several bases and policies in the same directory?

With recent versions of RunDynam (RunMONASH etc), it is relatively easy to set up and run several different base cases and several different policy runs, all in the same directory.

There is a very detailed example in the RunDynam Help file. To find that example, go to the chapter "Several Complete Applications in the Same Directory" in that Help file. Then find the topic "Several Bases, Policy Closures and Shocks in Same Directory" which is currently the fourth topic in that chapter.

After you read that example carefully, you should be able to adapt the techniques to your own work.

Question 2. How can I efficiently store several bases and policies in the same directory?

There is a very detailed example in the RunDynam Help file. To find that example, go to the chapter "Several Complete Applications in the Same Directory" in that Help file. Then find the topic "Archiving and Restoring Several Applications in the Same Directory" which is currently the fifth topic in that chapter.

This all relates to the different Base and Policy runs considered in the answer to Question 1 above.

Notice that the 8 different applications can be stored using just one full ZIP archive and one closure/shocks ZIP archive. Of course the latter is much smaller than the former.

Question 3. How can I efficiently move in RunDynam between several bases and policies in the same directory?

Good advice is given in the topic in the Help file indicated in the answer to Question 1 above. In particular, note how the SLOW policy shocks are loaded in case 4 in that Help topic - just load part of the Sim details (in that case, just the Policy Shocks part of the MYMODEL-NORB-PRER-SLOP.DS1 Sim details).

Once you have run one application with the desired part in it, you can load it into RunDynam by loading just that part from the Sim details which were saved by RunDynam when you ran that application.

Of course, you can Save Sim details (under the file menu) any time you set up part of an application (for example, new Policy closures). You don't have to rely on a run of the application to save the Sim details.

ZIP Archives for the Example

You can download a ZIP archive and a closure/shocks ZIP archive which are the two saved in the answer to Question 2 above. From these 2 zip files, you should be able to set up and run the 8 different applications described in the answer to Question 1 above. The model in MO2.TAB is a slightly odd version of the Miniature ORANI model - a version we use in our testing of RunDynam developments. Although the model is slightly odd, you should be able to use it to practice the ideas in the answers above.
