What is DACCOSIM NG?
DACCOSIM NG is an environment to develop and run co-simulation use cases supported by JavaFMI, a suite of tools for interoperability using the co-simulation part of FMI standard. DACCOSIM allows the design and execution of co-simulations, providing mechanisms to develop co-simulation graphs.
DACCOSIM NG project has two components: an Editor (Graphical User Interface) and a Shell (Command-Line Interface). Following sections briefly explain how to use them. Detailed information can be found here. Additionally, we have these tutorials:
DACCOSIM NG Editor
The editor allows the design of co-simulation graphs using a graphical interface. To do so, blocks must be dragged from the palette (on the left) into the canvas (in the center). If an FMU block is dragged, the FMU file that is to be used will be asked by the editor. Once all blocks are placed in the canvas, their data exchanges can be defined through arrows. To define an arrow, just drag from the center of the source block and drop it in the center of the target block.
Once the co-simulation graph is defined, the correctness of the graph can be checked by using the button . In case there is something wrong, the editor will indicate what is the problem.
In the button , the execution can be configured: start and stop time, kind of stepper, variables to export...
After configuring the co-simulation graph, it can be executed by clicking in .
DACCOSIM NG Shell
The Shell allows the execution of co-simulation graphs using a command-line interface. The arguments that can be used in this CLI are:
- outputBuffer:32 (expressed in KB))
An example of use is:
java -jar shell.jar input:file.simx multithreaded:false
- Co-initialization: consistent system-wide initial values setting for all the components thanks to a parallelized Newton-Raphson algorithm
- Co-execution: co-simulation execution either with constant or adaptive steppers using single-step or multiple-steps methods
- Architecture: designed to execute co-simulations either on multi-core machines or distributed on multi-machine environment
- Matryoshka: efficient encapsulation of a co-simulation into a parallel FMU
- Domain Specific Language: large-scale co-simulation design via text files that can be automatically generated by third-party tools
