info = modelicaInfo()
| Parameter | Description |
|---|---|
| info | a scalar structure describing the OpenModelica installation, with the fields listed below. |
modelicaInfo reports the OpenModelica compiler (omc) that the nflow Modelica bridge will use. A modelica block compiles a Modelica model to an FMU with OpenModelica and then simulates it through nflow's FMI path; modelicaInfo tells you whether that is possible and which OpenModelica is selected.
The returned structure info has the following fields:
| Field | Class | Details |
|---|---|---|
| available | logical | true when an omc executable was found and runs. |
| capable | logical | true when OpenModelica is not only present but able to export an FMU (the FMI export runtime is installed). A model simulates only when capable is true. |
| omc | char | the resolved path to the omc executable, or an empty string. |
| home | char | the OpenModelica home directory, or an empty string. |
| version | char | the version string reported by omc. |
| reason | char | a human-readable status; when not usable, it explains why and how to fix it. |
Presence is not capability: an omc executable can run yet be unable to build an FMU when its installation is missing the FMI export runtime. Concretely, the probe checks for the directory share/omc/runtime/c/fmi under the OpenModelica home; when it is absent (an incomplete install, without the C runtime / FMI export support), available is true but capable is false, and a modelica block blocks the simulation with a clear message. Install a complete OpenModelica, or point nflow at one with modelicaConfigure.
The OpenModelica location is resolved from, in order: a path configured with modelicaConfigure (authoritative when set), the NELSON_OPENMODELICA_HOME environment variable (Nelson-scoped), the OPENMODELICAHOME environment variable, the standard install directories, then PATH.
