## On this page # Fluids Last update: 13.08.2026 The Ansys Common Fluids Format SDK provides APIs, data models, and example programs to access or write data to Ansys Common Fluids Format files. This format is also used by Ansys Fluids products. For more information, see [Ansys Common Fluids Format SDK for developers (Developer Portal documentation)](https://developer.synopsys.com/docs/cff). ## BladeModeler There are no developer tools available at this time. ## CFX Ansys CFX includes a command language (CCL) and an expression language (CEL). CCL uses embedded Perl, and user-generated models are applied using User Fortran. PyCFX, part of PyAnsys, is also available and is compatible with Ansys CFX 2025 R2 Service Pack 3 and later. - [PyCFX documentation (PyAnsys)](https://cfx.docs.pyansys.com/) ### Ansys CFX training material - [Ansys CFX Customization (ALH)](https://www.ansys.com/training-center/course-catalog/fluids/ansys-cfx-customization) - [Ansys 2026 R1: Ansys Fluids What's New (Webinar)](https://www.ansys.com/en-gb/webinars/ansys-2026-r1-ansys-fluids) ### Non-Ansys CFX training material - [CFX Expression Language - Part 1: Accessing CFD Simulation Information in CFX (and FLUENT) (PADT)](https://www.padtinc.com/2013/04/04/cfx-expressions-part-1/?utm_source=rss&utm_medium=rss&utm_campaign=cfx-expressions-part-1) ## Chemkin As of Ansys Chemkin 2025 R2 there is now a PyChemkin PyAnsys library. - [PyChemkin documentation (PyAnsys)](https://chemkin.docs.pyansys.com/version/stable/) ## EnSight EnSight includes a command-language journaling feature and an embedded Python interpreter. - [Post-processing for developers, which includes Ensight (Developer Portal documentation)](https://developer.synopsys.com/docs/post-processing) - [PyEnsight documentation (PyAnsys)](https://ensight.docs.pyansys.com/version/stable/) - [PyEnSight Visual Studio Code Extension](https://marketplace.visualstudio.com/items?itemName=AnsysDevelopers.pyensight) ### Ansys EnSight training material - [EnSight Python Scripting (ALH)](https://www.ansys.com/training-center/course-catalog/fluids/ensight-python-scripting) - [EnSight: Python Macros and User-Defined Tools](https://www.youtube.com/watch?v=SJkViorO3Gw) ### Non-Ansys EnSight training material - [Ansys EnSight - Automate Post Processing with Python (DRD Technology)](https://www.youtube.com/watch?v=gFMxSvXJQis) - [How To Write a Python Script for EnSight (CEI)](https://ceisoftware.zendesk.com/hc/en-us/articles/203896296-How-to-write-a-python-script-for-EnSight) ## FENSAP-ICE There are no developer tools available at this time. ## Fluent Ansys Fluent includes both a GUI and a Text User Interface (TUI), which is a user interface that displays text, symbols, and ASCII characters for interaction instead of graphical elements. The TUI uses a dialect of Lisp named [Scheme](https://en.wikipedia.org/wiki/Scheme_(programming_language)). For more information about the Fluent TUI, see [Text user interface](https://ansyshelp.ansys.com/public/account/secured?returnurl=/Views/Secured/corp/v242/en/flu_ug/tgd_tcl_tui.html) in the Fluent product documentation. Fluent provides an open-source Python interface named PyFluent, which is part of PyAnsys. It also includes two complementary PyAnsys libraries: PyFluent-Parametric for parametric studies and PyFluent-Visualization for visualizing results. - [PyFluent documentation (PyAnsys)](https://fluent.docs.pyansys.com/version/stable/) - [PyFluent-Parametric documentation (PyAnsys)](https://parametric.fluent.docs.pyansys.com/version/stable/) - [PyFluent-Visualization documentation (PyAnsys)](https://visualization.fluent.docs.pyansys.com/) The TUI is accessible within PyFluent, but with limitations. For more information, see [Using TUI commands](https://fluent.docs.pyansys.com/version/stable/user_guide/legacy/tui.html) in the PyFluent documentation. ### Ansys Fluent training material Few developer-exclusive training resources are available for Fluent.
