Getting started

This guide describes how to use midas to run some simple simulations.

Prerequisites

It is assumed that you have already followed the instructions of the Installation guide.

First start

Read this section carefully, before you type any command. On the first start of midas, a short configuration routine is triggered. midas will create an .ini file to store basic configurations. midas will ask for permission to create a folder in your home directory to store the midas.ini file. If you do not want to create such a folder, the midas.ini file will be created in the current directory. If you start midas again from another location, the configuration routine will be triggered again unless you move the previously created .ini file to the new location as well.

In the next (and last interactive step) of the configuration, midas asks where the datasets should be stored. The default location is, again, the midas folder in your home directory, but you can specify any other folder you like. The recommend way is, of course, to use the folder in your home directory.

Now type into your console:

(midas) $ midascli

If you want to use the recommended configuration, just hit enter for both prompts. If you do so, the program will start downloading the datasets.

Running a simple scenario

If you selected the default answers for both prompts, the program is probably still downloading the data or running the simulation. If not, you should have a look at the created .ini file, use the console again, and type:

(midas) $ midascli -d

This will do two things: First, midas checks if the data sets are available in the folder specified during the setup. If that is not the case, the data sets will be downloaded into that folder.

Secondly, the default scenario midasmv will be started, which consists of a CIGRE medium voltage grid and household data attached to it. Using the -d flag, all data will be pushed into a mosaik-hdf5 database.

Congratulations! You have successfully run a co-simulation with midas.
