PARAVIEW CLUSTER HOW TO
PARAVIEW CLUSTER INSTALL
PARAVIEW CLUSTER GENERATOR

While Gmsh is a graphical application, users are encouraged to leverage Gmsh in a headless mode to process Gmsh scripts or with ` pygmsh `_.

PARAVIEW CLUSTER INSTALL

The provided install of Gmsh has OpenCascade enabled, which allows you to create mesh files starting from OpenCascade CAD files.

PARAVIEW CLUSTER GENERATOR

The RCC-CFD VM image includes ` Gmsh `_, an open-source mesh generator capable of creating mesh files for OpenFOAM simulations. * :code:` /etc/profile.d/z11_paraview.sh` defines the necessary environment variables for exposing the Paraview binaries to each user automatically when they log in. * :code:` /opt/share` hosts a PVSC XML file and template job submission script that are used to connect your local Paraview client to a Paraview Server running in Google Cloud through RCC * :code:` /opt/paraview` hosts Paraview binaries and shared object libraries for Paraview dependencies These scripts include a PVSC XML file in addition to a template job submission script that handles launching paraview server on compute nodes as well as establishing a reverse ssh connection to your local client. We've also included scripts that can help you easily connect a local Paraview client on your workstation to a Paraview server running in Google Cloud underneath :code:` /opt/share/`. When a user logs in, the :code:` /etc/profile.d/z11_paraview.sh` script is sourced automatically so that Paraview is found in the default serach path. Paraview is installed under :code:` /opt/paraview`. The EGL backend allows for you to take advantage of Nvidia GPUs for many rendering tasks as well. MPI-built paraview allows for parallel rendering, a particularly useful feature for large datasets. Paraview is installed using pre-compiled downloads from with MPI and EGL enabled. Paraview is commonly used for visualizing OpenFOAM model output, in addition to output from other CFD applications. The RCC-CFD VM image includes ` Paraview `_, a scalable tool for scientific data visualization. * :code:` /etc/profile.d/z10_spack_environment.sh` defines the necessary environment variables for exposing the Spack environment to each user automatically when they log in. * :code:` /opt/share` hosts the simulation case directories for the Aerofoil and Dam Break (2.8M) benchmarks for proof-of-concept with this image. * :code:` /opt/view` hosts a consolidated view for the Spack environment using symlinks from `/opt/spack` * :code:` /opt/spack-pkg-env` hosts the Spack environment file that dictates what packages and versions are installed alonside which compiler is used to install them. * :code:` /opt/spack` hosts the Spack package manager and all of the packages installed by Spack. The directories for each of these cases can be found under :code:` /opt/share` To help you quickly prove concept for running OpenFOAM on Google Cloud, we've provided job submission scripts and input decks for the ` Aerofoil `_ and ` Dam Break (2.8M) `_ benchmarks. When a user logs in, the :code:` /etc/profile.d/z10_spack_environment.sh` script is sourced automatically, so that OpenFOAM binaries are made available upon login. To expose OpenFOAM and the other necessary binaries to each user's default :code:` $PATH`, all package binaries are symlinked to :code:` /opt/view/bin`. A Spack environment file, which dictates the specific package versions and compilers, is maintained under :code:` /opt/spack-pkg-env`. All packages are installed under the :code:` /opt/spack` directory. The RCC-CFD VM image uses ` Spack `_ to install a compiler, MPI flavor (OpenMPI for all builds), OpenFOAM, and the necessary dependencies. Marketplace images are quality controlled and benchmarked before release and additionally include the cluster-services CLI tool for customizing your cluster post-deployment. The RCC-CFD VM Image is built using the open-source ` RCC-Apps `_ image baking repository. If you'd like to deploy RCC-CFD using Terraform, see the :doc:` Deploy with Terraform ` documentation. If you'd like to deploy RCC-CFD from the Google Cloud Marketplace, see the :doc:` Deploy from Marketplace ` documentation.

PARAVIEW CLUSTER HOW TO

How to add OpenFOAM to an existing clusterĤ. What is included in the RCC-CFD VM ImagesĢ. Alternatively, if you want to get started with a click-to-deploy solution that has OpenFOAM, Paraview, and GMSH installed, you can use the ` RCC-CFD Marketplace solution `_.ġ. The Research Computing Cluster (RCC) offers OpenFOAM and Paraview through virtual machine images that can be easily incorporated into an existing RCC. ` Paraview `_ is an open-source toolkit for visualizing scientific data and is capable of leveraging clusters of compute instances for rendering large datasets. ` OpenFOAM `_ is an open-source finite-volume based computational fluid dynamics toolkit for simulating a variety of fluid phenomena.
