Hi, I want to study flutter condition of an airfoil so I think that the best way is to do a 2-way FSI with System Coupling. I have the Free Student Software of Ansys so I want to know if my license admits this module. 

Also I have seen on Tools->License preferences, that I have three different licenses:

1-Ansys AIM Student

2-Ansys Academic Teaching Introductory

3-Ansys Discovery Live Student

Does any of these licenses admit System Coupling?

Hi Simon95,

I'm not 100% but I think ANSYS Student license should allow FSI solve since the Mechanical and CFD solvers are called sequentially/separately and they should just use their own licenses.

Make sure you set this setting in the User License Preferences -> Use a separate license for each application  .  Make sure to restart Workbench after this setting if you are opening it.

Thanks,

Win

Hi tsiriaks,

First of all thank you for your responde. I agree with you that Ansys should allow FSI. I have already done what you say about User License Preferences. I have closed the workbench and opened it again (I think you refer to that when you say restart the workbench).

However, after that I enter in the System Copling module and no participant appear. The program show me this error: (DP 0) The Setup component in Fluid Flow (Fluent) requires user input before it can be updated. For instructions on how to address the cell in its current state, click the blue triangle in the lower right corner of the cell in the Project Schematic.

I have already connect the setup of both transient structural and fluid flow to system coupling one.

May can you help me, please? Thank you

Hi Simon95,

ANSYS Academic Teaching Introductory will allow you to use Mechanical and Fluent, however it will not allow you to use them simultaneously. In order to use both Mechanical and Fluent simultaneously, you'll need two seats of this license and, as Win noted, you'll need to use a separate license for each application. System coupling requires each solver to have a separate academic license.

Ryan

Hi Ryan,

Thank you for your response, I think now I understand how ANSYS works in that case. However, I do not know how to achieve the two seats I need of ANSYS Academic Teaching Introductory. The only think I can do is to change the default settings to "use a separate license for each application". I add an image of it.

If you can guide me through this process I would be very thankful. I hope you know how to act in this situation.

Thank you for your time and dedication.

Hello simon,

May i know what are the steps u followed to view ur available licenses?

 

Thanks

Hi Simon95,

You'll need to purchase a second seat of the ANSYS Academic Teaching Introductory license in order to perform a system coupling simulation.

Hi Simon95,

Sorry, I was incorrect in my last post. Since you have the ANSYS Academic Teaching Introductory license you should have unlimited seats. It also sounds like you're setting up your license preferences correctly to use a separate license for each application. Can you provide more details on the error you're encountering as detailed below:

"However, after that I enter in the System Copling module and no participant appear. The program show me this error: (DP 0) The Setup component in Fluid Flow (Fluent) requires user input before it can be updated. For instructions on how to address the cell in its current state, click the blue triangle in the lower right corner of the cell in the Project Schematic."

At what stage do you encounter this error? Simply by editing the setup cell?

Ryan

Hi Ryan,

Thank you for your patience and your information. Finally I have been able to open the System Coupling. System coupling is reading participants (fluent and structural), so I have managed to make it work thanks to your advice. Now I have a different error when I´m triying to update solution, but this is another topic.

Thank you again for your interest.

Regards,

Simon
