How to Transfer a Thermal Field from Ansys Fluent to Ansys Mechanical
Hello, my name is Jesus Ramirez, and I am part of the technical staff at Ozen Engineering, Inc. Today, I will demonstrate how to transfer a thermal field from Ansys Fluent to Ansys Mechanical.
Initial Setup
We start with a simple geometry, which consists of a basic arrangement of pipes. This geometry includes:
- A solid geometry
- A fluid part for CFD analysis
There are several named selections:
- An inlet
- A small inlet
- An outlet
CFD Analysis
Initially, we perform a CFD analysis with the energy equation enabled. The goal is to transfer the thermal field from Ansys Fluent to Ansys Mechanical for structural analysis.
In Ansys Fluent, we set up the following boundary conditions:
- 5 m/s velocity at 750 Kelvin at one boundary
- 2.5 m/s velocity at 300 Kelvin at another boundary
These flows mix, causing a temperature variation on the pipe wall, which we aim to extract for Ansys Mechanical.
Transferring Thermal Field to Ansys Mechanical
With the case solved in Ansys Fluent, we proceed to transfer the information to Ansys Mechanical using Ansys Workbench:
- Load the Ansys Fluent solution in the Fluent module.
- Drag a static structure module into the main window of Workbench.
- Use the solid geometry for this case and move it to the main window.
- Open Mechanical by double-clicking the model.
- Create a mesh with a size of 1-2 mm for simplicity.
- In the "Import Load" section, right-click and select "Insert" > "Temperature".
- Select the body for which you want to import the thermal field and set the source term to the full value.
- Click "Import Load" to transfer the data from Fluent.
The temperature data is now imported from Fluent to Mechanical by interpolation.
Structural Analysis
Before solving, we add constraints:
- Insert fixed supports to avoid solution problems.
- Insert stress analysis options such as total deformation and thermal strain.
Once solved, you can review the thermal stresses and total deformation.
Conclusion
This process provides an efficient way to transfer a thermal field from Ansys Fluent to Ansys Mechanical. If you have any questions, feel free to contact us at support@ozen.com. We are happy to help.
Thank you so much. Bye bye.
Hello, my name is Jesus Ramirez and I am part of the technical staff of AUSEN Engineering. Today I am going to show you how to transfer a thermal field from ANSYS Fluent to ANSYS Mechanical.
For this, I will start with this geometry, which consists of a solid geometry and a fluid part for the CFD analysis. I have named selections for an inlet, a small inlet, and an outlet. Initially, I will perform a CFD analysis with the energy equation ON.
After obtaining the solution, I will transfer the thermal field from ANSYS Fluent to ANSYS Mechanical for structural analysis. In ANSYS Fluent, I have obtained the thermal field, which I will extract for ANSYS Mechanical.
The case is already solved, and I want to transfer this information to Mechanical for structural analysis. To do this, I will use the ANSYS Workbench.
With the ANSYS fluid solution already loaded in the Fluent module, I will take a static structure module and drag it into the main window of Workbench. The geometry for this case will be the solid geometry, and I will import the thermal field after setting up constraints and meshing.
Now, I have a mesh and will import the thermal field from Fluent by interpolation. After that, I will solve the system and check the thermal stresses and total deformation. With this, I have shown you an easy way to transfer a thermal field from ANSYS Fluent to ANSYS Mechanical.
