### What is SimAPI? Engineering simulation has evolved from its origins of mainframe computers and punch cards for simple analyses to powerful desktop multiphysics simulations described by complex application-specific inputs. Now cloud computing is revolutionizing the possibilities of simulation, but a major hurdle for engineers remains the difficulty of fitting a multitude of new applications into their concept, design and production workflows. SimAPI (short for Simulation API) overcomes this hurdle by defining simulations using universal scientific programming languages like python and Matlab. The many benefits of this approach include: * Simulations that fit into already established workflows * Simple to learn * The power of built-in scripting * Ability to use the wide range of already existing libraries for pre- and post-processing * Portability of the simulation description across different applications * Ease of interfacing with cloud-computing solutions Combined with OnScale’s Cloud Client, SimAPI offers engineers the ability to seamlessly run large simulation studies with almost limitless computing resources from within their own established workflows.
