Innovative Solvers for Unprecedented Numerical Accuracy
For engineers trying to model transients in real-time, the inherent error introduced by currently available fixed-timestep integration algorithms has been a major problem. Variable-step solvers, such as those provided by MATLAB and other advanced mathematical tools, could not be used because of their non-deterministic execution times. The new ARTEMIS fixed-step solvers developed by Opal-RT provide the best of both worlds: real-time performance with variable-step accuracy.
