This public resource center contains information related to how anyone can easily gain access to HPC resources and expertise.
What is HPC? There are lots of terms that essentially are variations of the same thing: HPC (High Performance Computing), Advanced Modeling, Simulation & Analysis, Technical Computing, Cluster Computing, Parallel Computing. Specifically, these refer to computers at the frontline of current computational processing capacity.
Why would you use HPC? For some situations, experimentation may not be adequate to test theories because things may be too small to see and measure, systems may be too large and remote, or processes can be too fast or too complex. Alternatively, simulations or analyzes may take too long or the size of the data is too large to be contained on a personal computer.
Regardless of your experience level with HPC, in order to fully utilize it, you need access to three main components: hardware, software, and expertise.
HPC Hardware can consist of cloud based resources, small departmental level clusters, or even powerful workstations, etc.. These are available from a variety of vendors, ranging from online ‘pay-as-you-go’ access, to large systems custom designed and installed in dedicated data centers.
CAE software can comprise of things such as solvers, meshers, visualization, and workflow managers, etc.. This software can range from very specialized, open-source packages available at no cost, to more generic commercial packages that can run across a wide scale of domains and resources.
Expertise that is available includes domains such as Computational Fluid Dynamics, Finite Structural Analysis, Bioinformatics, etc. Companies needing expertise often start with external consulting “engineering service providers” who can assist with a specific project, before eventually directly hiring domain experts versed in a variety of technical skills.

This thermomechanical simulation consists of a quarter of a solid cylindrical object with an imposed temperature field. The predicted stress due to thermomechanical expansion from the simulation results is compared against the reference solution given by the NAFEMS benchmark book.
This simulation consists of a steel W-beam with a remote force applied at an offset from one end face and the other end face is fully fixed. The predicted deflection at the free end of the beam from the simulation results is compared against the reference solution given by Roark’s Formulas for Stress and Strain.
