CFD in Ansys Discovery - Refine Mode
Hi everyone, this is Mingyao from Ozen Engineering, Inc. and this is a demonstration of the Ansys Discovery CFD capabilities for 2024. There are many new features available, so I thought I'd make a quick video to showcase them.
Setup and Import
What you see on screen is me remotely logging into a workstation with a good GPU. Let's take a look at some of these features. I'm going to import a SOLIDWORKS assembly here. I'm accessing a remote computer using my web browser, which is pretty cool. One of the things I like about SOLIDWORKS is that it's very easy to access the software.
New Features in Ansys Discovery
The main new feature in Ansys Discovery simulation is the inclusion of the Refine Mode for CFD solvers. This makes it possible to run high-quality CFD simulations directly from the Discovery interface, which is easy to use.
Fluid Volume Recognition
Here's the internal flow we're trying to capture: the fluid volume inside a plug valve. Discovery is really smart and automatically recognizes the fluid volume, organizing the inlet and outlet. After a few seconds, it automatically extracts the fluid volume, which used to require manual operations.
Boundary Conditions
Now, let's add some boundary conditions:
- Inlet: 1 meter per second flow
- Outlet: Defined as the exit point
After setting these, I noticed a duplicate inlet, which I deleted. This allowed the run button to appear.
Meshing and Simulation Controls
Meshing is crucial for accurate results in CFD simulations. Here's a quick overview of the meshing process:
- Automatic refinement based on curvature and proximity
- Boundary layers are created for better flow capture
- Mesh controls are tied to turbulence models
Simulation Controls
Under simulation controls, you can specify:
- Solver type
- Convergence criteria
- Modeling methods
You can choose different turbulence models, such as the Spalart-Allmaras model.
Running the Simulation
Let's run the simulation using the GPU solver. Monitoring the results is helpful, for example, by tracking the maximum pressure. The simulation quickly converges to a stable pressure value, thanks to the high-speed GPU solver.
Visualization and Analysis
Discovery provides excellent visualization tools:
- Vector plots to show flow direction and rotation
- Pressure and velocity plots
- Section planes for cross-sectional views
You can adjust convergence settings, meshing methods, and explore different design changes interactively.
Conclusion
In conclusion, Ansys Discovery 2024 offers fantastic new capabilities for CFD simulations, including advanced turbulence models and both GPU and CPU solvers. If you haven't seen this already, please visit OzenInc.com. We'd be happy to show you how this can be applied to your needs.

Hi everyone, this is Mingyao from OZEN Engineering and this is a demonstration of ANSYS Discovery CFD capabilities. It's 2024, and there are many new capabilities available in ANSYS Discovery CFD.
I'm remotely logging into a workstation with a good GPU, and I'll take a look at some of these features. I'm importing a SOLIDWORKS assembly and accessing a remote computer using my web browser.
One of the main new features in ANSYS Discovery simulation is the refine mode for CFD solvers, which makes it possible to run good CFD simulations right from the Discovery interface. We're trying to capture the fluid volume inside of this plug valve.
Discovery automatically recognized the fluid volume, and we can choose to hide everything else. We can add flow boundary conditions, such as a one-meter-per-second flow at the inlet and outlet. We can also add a turbulence layer and specify the type of solver, convergence, and modeling methods.
For those used to doing CFD simulations, meshing is important for accurate results. We can generate a mesh and control the mesh based on curvature, proximity, or both. We can also specify a value for local refinement around a particular region.
We can monitor the results, such as the maximum pressure, and adjust convergence settings. The tool allows us to control accuracy by adjusting the mesh appropriately and setting up the simulation with the right boundary conditions.
We can interactively change the geometry, such as the valve position, and the solver will automatically mesh and run the new model. We can also adjust the convergence and specify meshing methods.
Discovery has standard post-processing tools, such as plotting multiple variables and probing specific locations. We can also do a section plane and see the flow paths. Thank you for your time. If you haven't seen this already, please let us know at OzoneInc.com.
We'd be happy to show it to you or discuss how this can be applied to your needs.
