💥💥💥 How to communicate Ansys Fluent with Siemens Simit (possible ways) ?

 To communicate Ansys Fluent with Siemens Simit, you may need to use the Functional Mock-up Interface (FMI) standard, which is a tool-independent standard for the exchange and co-simulation of dynamic models. FMI defines a common interface for model exchange and co-simulation, which allows different simulation tools to communicate and exchange information during the simulation process¹.

One possible way to use FMI is to create a sub circuit using compatible elements in Twin Builder, and then compile a twin model out of the sub circuit. After that, you can select the twin model and export it as a twin for deployment². You can also use the command /plot/file-set/plot-to-file [filename] to export the data used in the plots into a specified file³. However, Fluent only supports co-simulation FMU, which means that it cannot export FMU files by itself⁴. You may need to use another tool that supports FMI model exchange to create FMU files from Fluent data.

Can I import output results file, for example CSV file from Ansys Fluent to Simit, without using Twin Buidler?

It seems that you want to import output results file, for example CSV file from Ansys Fluent to Simit, without using Twin Builder. According to the web search results, there are some possible ways to do that by using the Functional Mock-up Interface (FMI) standard, which is a tool-independent standard for the exchange and co-simulation of dynamic models. FMI defines a common interface for model exchange and co-simulation, which allows different simulation tools to communicate and exchange information during the simulation process¹.

One possible way to use FMI is to export the data used in the plots into a specified file by using the command /plot/file-set/plot-to-file [filename]². Then, you can use another tool that supports FMI model exchange to create FMU files from Fluent data. For example, you can use Simulink, which is a graphical environment for modeling, simulation and analysis of multi-domain systems. Simulink can import and export FMU files and perform co-simulation with other FMI-compatible tools³.

Another possible way to use FMI is to write the result of Fluent into a generic ASCII file which you can then read elsewhere⁴. Then, you can use a tool that can convert the ASCII file into an FMU file, such as FMPy, which is a Python library to simulate FMU files⁵.

What is the difference between FMI and FMU?

The difference between FMI and FMU is that FMI is a standard for the exchange and co-simulation of dynamic models, while FMU is a file that contains a simulation model that adheres to the FMI standard¹. FMI defines a common interface for model exchange and co-simulation, which allows different simulation tools to communicate and exchange information during the simulation process. FMU is a file that consists of an XML description file and implementation in a binary form². FMU can be imported or exported by different simulation tools that support the FMI standard. FMI and FMU are part of the same FMU standard for the purpose of system integration, which simplifies the interaction between the simulation environment and the systems models in different domains³. FMU represents the simulation model, while FMI provides a standardized communication interface between the models.

Is there possibility to create FMU file in Ansys Fluent ?

No, there is no possibility to create FMU file in Ansys Fluent. Fluent only supports co-simulation FMU, which means that it can import but not export FMU files¹. FMU files are files that contain a simulation model that adheres to the Functional Mock-up Interface (FMI) standard, which is a tool-independent standard for the exchange and co-simulation of dynamic models². If you want to create FMU files from Fluent data, you may need to use another tool that supports FMI model exchange, such as Ansys Twin Builder, Simulink, or FMPy³. You can also use the command /plot/file-set/plot-to-file [filename] to export the data used in the plots into a specified file⁴. 

What modules in Ansys Workbench have possibility to create FMU file ?

According to the web search results, it seems that there are some modules in Ansys Workbench that can create FMU files. FMU files are files that contain a simulation model that adheres to the Functional Mock-up Interface (FMI) standard, which is a tool-independent standard for the exchange and co-simulation of dynamic models¹.

Some of the modules that can create FMU files are:

• Ansys Twin Builder: Ansys Twin Builder is a platform for creating, validating and deploying digital twins. Twin Builder can import and export FMU files and also compile a twin model out of a sub circuit².
• Ansys Simplorer: Ansys Simplorer is a multi-domain system simulation software for the design of complex power electronic and electrically controlled systems. Simplorer can generate FMU files from Simplorer models and also import FMU files from other tools³.

How do I create an FMU file from Ansys Mechanical data?

To create an FMU file from Ansys Mechanical data, you need to use the FMI Export feature in Ansys Mechanical. FMU files are files that contain a simulation model that follows the Functional Mock-up Interface (FMI) standard, which is a tool-independent standard for the exchange and co-simulation of dynamic models¹.

The FMI Export feature allows you to export your Mechanical model as an FMU file for co-simulation with other FMI-compatible tools. You can access the FMI Export feature by right-clicking on the Solution branch in the Mechanical outline and selecting FMI Export². You can then specify the name and location of the FMU file, the FMI version, the co-simulation type, and the input and output variables. You can also select the option to include the results file in the FMU file, which will allow you to initialize the FMU with the results from the Mechanical solution³.

After you export the FMU file, you can import it into another tool that supports FMI co-simulation, such as Ansys Twin Builder, Simulink, or Open Modelica. You can then perform co-simulation between the Mechanical model and the other model, and exchange data and parameters between them.
