![]() All packages are installed under the :code:` /opt/spack` directory. A Spack environment file, which dictates the specific package versions and compilers, is maintained under :code:` /opt/spack-pkg-env`. 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`. 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. 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. * :code:` /opt/spack` hosts the Spack package manager and all of the packages installed by Spack. * :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/share` hosts the simulation case directories for the Aerofoil and Dam Break (2.8M) benchmarks for proof-of-concept with this image. * :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. The RCC-CFD VM image includes ` Paraview `_, a scalable tool for scientific data visualization. Paraview is commonly used for visualizing OpenFOAM model output, in addition to output from other CFD applications. Paraview is installed using pre-compiled downloads from with MPI and EGL enabled. ![]() MPI-built paraview allows for parallel rendering, a particularly useful feature for large datasets. The EGL backend allows for you to take advantage of Nvidia GPUs for many rendering tasks as well. Paraview is installed under :code:` /opt/paraview`. ![]() 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. 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/`. * :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. * :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. The RCC-CFD VM image includes ` Gmsh `_, an open-source mesh generator capable of creating mesh files for OpenFOAM simulations. The provided install of Gmsh has OpenCascade enabled, which allows you to create mesh files starting from OpenCascade CAD files. While Gmsh is a graphical application, users are encouraged to leverage Gmsh in a headless mode to process Gmsh scripts or with ` pygmsh `_. Gmsh is installed under :code:` /opt/gmsh`. Movie files from various viewpoints showing the shape changing. Only the most basic features of that excellent tool areĪvailable in this web based version. Interface to submit topology optimization jobsīi-directional Evolutionary Structural Optimization (BESO) method script written byįrantišek Löffelmann. You can install either Spooles, Pardiso or Intel'sĬluster sparse solver. Here is an interactive perl script that automates the Calculix build process on linux systems.
