Connect systems

The following example demonstrates how multiple systems can be connected for the simulation.

Consider the following systems.

For each input of a system it must be defined with which output of another system the input is to be connected. For the shown system the variables ‘fmu_infos’ and ‘model_infos’ must be defined as follows. The variables ‘fmu_infos’ and ‘model_infos’ are inputs for the simulate() function.

>>> fmu_infos = [
... {"name": "FMU1",
...  "path": "<path to the fmu>",
...  "connections":
...     [
...     {
...         "parameter name": "fmu1_input1",
...         "connect to system": "CustomSystem1",
...         "connect to external parameter": "custom_system1_output1"
...         }
...     ]
...     },
... {"name": "FMU2",
...  "path": "<path to the fmu>",
...  "connections":
...     [
...     {
...         "parameter name": "fmu2_input1",
...         "connect to system": "FMU1",
...         "connect to external parameter": "fmu1_output2"
...        }
... }
... ]
>>> model_infos = [
... {"name": "CustomSystem1",
...  "connections":
...     [
...     {
...         "parameter name": "custom_system1_input1",
...         "connect to system": "FMU1",
...         "connect to external parameter": "fmu1_output1"
...         },
...     {
...         "parameter name": "custom_system1_input2",
...         "connect to system": "CustomSystem2",
...         "connect to external parameter": "custom_system2_output1"
...         }
...     ]
...     },
... {"name": "CustomSystem2"} # CustomSystem2 has no input so not connections need to be defined
... ]
