Is it possible to make meshing loop until a certain solution condition? In ANSYS workbench we can put parametric variables and use python script. I think it is possible to make some conditional statesment or script for getting proper mesh to satisfy user's results(not 1E-4) in ANSYS Fluid solver. I know some script is possible in ANSYS Mesher but I want to make a loop between Ansys Mesh and ANSYS CFX Post by using parameters and python script. Do I have to study APDL or API?

Hello jinwhan,

It is possible to make a loop between Ansys Mesh and Ansys CFX post by using python script. 

I would recommend you to use the latest version 2023 r2 . It has the following features . Please learn the API which will help you in scripting.

I have mentioned the capabilities of the API in the latest version.

In 2023 R2, Fluent API expansions includes:

• Discrete phase models (DPM), radiation, species transport, VBM
• Mesh interfaces
• Poor mesh numerics, solution methods, and controls
• File-related commands
• TUI journal to Python journal converter
• Automates conversion of customer .jou file to .py file
• Wild card support for named objects

 2023 R2 updates for PyFluent include:

• Field data improvement, including meshing mode implementation.
• Improved streaming services to support multiple data consumers and more multiple client connections.
• Batch-execute multiple operations in a single remote call.

PyFluent requires version 2022 R2 or later installed locally. 

New workflow enhancements for CFX in 2023 R2 include a new system coupling capability for a more streamlined workflow between Ansys Mechanical and CFX for aeromechanics analysis. You can now easily transfer complex mode shapes from Mechanical Modal Analysis to CFD Aerodynamic Damping Analysis in CFX. System Coupling enables automatic geometry alignment between Mechanical and CFD models.

I hope this helps you.

Thanks,

Is it only possible in ANSYS Fluent? Is there any example related to mesh contolled by solver?

Hello Jinwhan,

 It is also possible in Ansys mechnical and also in system coupling. As I have mentioned in my previous post, there is related knowledge material for example if you learn all those courses.

I hope this helps,

Thanks,
