Meshing Fidelity in Explore Mode in ANSYS Discovery
Hello everyone, this is Mohsen Seraj. I'm an application engineer for ANSYS CFT at Ozen Engineering, Inc. Today, I want to talk about meshing in Explore mode in ANSYS Discovery.
Introduction
We have already created the geometry and will discuss the cooling of a room, similar to a server or UPS room. The room contains a solid box representing a cluster, UPS, or mainframe. We also consider a fan inside the room for cooling, represented by a cylinder.
Physics Setup
Let's first check the physics setup:
- Everywhere is air, except for the box representing the computing unit, which uses the default material for the solid.
- Heat generation for the computing unit is set at 100 watts.
Boundary Conditions
- Two inlets and two outlets are present.
- Two fans are located at the wall, and one fan is inside the domain.
- The inlets have the same velocity and temperature.
- Outlets are set as pressure outlets.
- Fans include:
- First fan at the wall on one side.
- Second fan on the opposite side.
- Intake part for the inside fan and exhaust part for the other side of the fan.
Connectivity
This is the default connectivity for the fluid-solid interfaces, ensuring the connection between the solid domain and the fluid domain.
Mesh Features in Explore Mode
Explore mode offers several features for mesh fidelity:
- Change mesh size using a slide bar to adjust mesh fidelity.
- Global fidelity options include:
- Standard
- Aggressive
- Extreme
These options reduce the size of the elements in the mesh.
- Custom option allows setting the level of mesh size fidelity.
- Local fidelity is a feature for mesh refinement in specific regions, currently unavailable but will be available in ANSYS 2024 R1.
Activating Local Fidelity
To activate local fidelity in ANSYS Discovery 2024 R1:
- Go to Files > Settings.
- Navigate to the Advanced section under Beta Features.
- Activate the local fidelity for fluid simulation in Explore mode.
Once activated, you can select specific faces or regions to change the mesh size locally.
Conclusion
In the second part, we will explore the impact of mesh fidelity on our results for this specific problem. Thank you for watching.
Title: Meshing Fidelity in Explore Mode in Ansys Discovery Hello everyone, this is Mohsen Seraj, an application engineer for ANSYS CFT at Ozen Engineering. Today, I want to talk about meshing in Xpolar mode in Ansys Discovery.
We have created the geometry of a room, which could represent a server room or UPS room. We want to talk about the cooling of this room, which contains a computing unit represented by a solid box.
We consider heat generation for this computing unit and have two inlets, two outlets, and two fans at the walls, as well as one fan inside the domain. The inlets have the same velocity and temperature, and the outlets have pressure outlets. The fans have intake and exhaust parts.
The fluid-solid interfaces have default connectivity. In Explore mode, we can change the mesh size, which we call mesh fidelity, using a slide bar. We can also change the mesh size globally or set a custom mesh size.
In Ansys 2024 R1, we will have local fidelity, which allows for mesh refinement in specific regions of the domain. To change the mesh size of the domain, check the settings in Files and Settings under the advanced part in beta features.
The local fidelity option is now available in Ansys Discovery 2024 for fellow simulation in explorer mode. Let's work on the features available for the fidelity of the mesh and see the impact on our results. Thank you.
