Even if we are talking about a reasonable interval for saved time steps, a large and fast NVMe SSD should definitely be part of the package.ħ950X3D: If we want to stick to consumer-grade hardware for maximum single-threaded performance, I would go with the regular 7950X. This is about 1GB of raw data for each time step. I hope you don’t intend to do processing for each time step in ParaView. 40-60 million gridpoints and 5 calculated values at each for a couple million timesteps Or if you don’t need to use OptiX, you could also use an AMD GPU. So you could save some money here by getting a lower-tier GPU with enough VRAM. For meshes with 50 million cells, 16GB of VRAM should be plenty. Additionally, the GPU memory determines how big of a model you can have visible. And if you are using ray tracing with OptiX, an Nvidia GPU will handle that. It helps with 2 things: how fluid it is to interact with the model. The GPU has little/no influence on how fast the data and filters are processed. I would appreciate any input!įor reference, the system I have chosen is: Ryzen 9 7950x3d, RTX 4090, 128gb 5200 mhz ddr5 ram. I am trying to decide if it is worth it to instead go for a server CPU with more cores but slower clock speeds (about 2.5 ghz instead of 4.5 base) and more RAM, get an A6000 instead of a 4090, or if the components I have chosen will do the job just fine. paraview openfoam Share Improve this question Follow asked at 15:44 94bb494nd41f 1 1 Are you following the installation guide verbatim Dependent ParaView installation is always pain in the neck. And, when using a GPU, paraview primarily uses the CPU to load each timestep and original model while the GPU does the heavy lifting of rendering.Īs such, I have tentatively chosen the Ryzen 9 7950x3d for the CPU and RTX 4090 for the GPU. From what I understand, ParaView utilizes all CPU threads when available, but can use GPU. These cases are rather large (~40-60 million gridpoints and 5 calculated values at each for a couple million timesteps). I primarily use ParaView to visualize OpenFOAM cases (reconstructed) that have been run on a remote cluster. 178 Simulation results highlighting the flow velocity.Hello, I am putting together components for a workstation and I am at a crossroads on a couple of decisions. The preset can be modified to better view the results by selecting the corresponding icon (highlighted in green).įig. #ĭifferent parameters can also be viewed, such as the flow velocity, and this can be done in the Coloring section by selecting U.

177 Simulation results highlighting the water phase. The resulting view of the water phase and block extraction is shown below:įig. 176 Available options for selecting the patches and changing the color. The patches of interest can then be either selected or deselected, and the Coloring can be set to Solid Color.įig. 175 List of filters available in ParaView, highlighting ExtractBlock. #įinally, to also add the walls and patches to the view, the Extract Block filter can be implemented (click on the channel.OpenFOAM file before applying it).įig. 174 Clip filter used for viewing the water phase in ParaView. To view the air phase, the Invert option should be selected whereas for the water phase it should be deselected.įig. The Clip Type should be set to Scalar, selecting alpha.water as scalar and setting the value to 0.5, which represents the interface between air and water. This can either be found in the Filters section in the menu, or alternatively, the shortcut can be used.

Next, to visualize only the water phase, the Clip filter is used. then in your case in openFoam, after making your mesh or finishing the run process, you should make a file which contains your cases informations by this command: Code: touch cavity (or any name you want).foam.

173 Options for changing the time step to be visualized. and download the paraView software for Windows and install it. To change the shown time step, the arrows that can be seen in the area highlighted in red can be used.įig. 172 Enabling the setting for viewing the air and water phases in ParaView. In order to visualize the air and water phases, alpha.water should then be selected in the drop-down menu as shown in the image below.įig. 171 Visualization of the case results in ParaView. Additionally, in the Fields section, the various fields that can be visualized are shown and can be selected/deselected according to the focus of the analysis.įig. The channel.OpenFOAM should now be present in the Pipeline Browser and to visualize it in the layout, press the Apply button.
