Welcome, @Bai0616! > [@Bai0616](#): > > can i coupling my own fluid fortran code with solid calculix code by precice? Yes, you can probably couple your own Fortran flow code with preCICE. Here is an overview of the steps you need to couple your code: [Couple your code | preCICE - The Coupling Library](https://precice.org/couple-your-code-overview.html) Specifically for Fortran, we have two [interfaces](https://precice.org/couple-your-code-api.html): - a legacy Fortran interface, included directly in preCICE ([example](https://github.com/precice/precice/tree/master/examples/solverdummies/fortran)) - a Fortran module: [GitHub - precice/fortran-module: A Fortran module for the Fortran bindings of preCICE (formerly "f2003 bindings")](https://github.com/precice/fortran-module) ([example](https://github.com/precice/fortran-module/tree/master/examples/solverdummy)) For CalculiX, you can use the [CalculiX adapter](https://precice.org/adapter-calculix-overview.html). See, for example, the [perpendicular flap tutorial](https://precice.org/tutorials-perpendicular-flap.html). > [@Bai0616](#): > > what can i do is fluid-adapter or other? I am not sure I understand this part of your question, but maybe I have already answered it above. ---

hi makis: i want to understand how to build the adapter of my fortran code with precice. i am not sure i uderstand the “Couple your code”, for example, i modify my fortran code withe precice module, and the next step what can i do ? ---
