AUTOMATED MESHING WITH AMR

Grid generation for IC engine simulations is never a problem with CONVERGE’s innovative meshing approach that generates the grid automatically at runtime. During a simulation, CONVERGE uses Adaptive Mesh Refinement (AMR) to increase the grid resolution when and where it is needed and to help you achieve grid-convergent analyses.

OPTIMIZATION

CONVERGE includes a genetic algorithm (GA) optimization tool that uses a survival-of-the-fittest approach to effectively think “outside of the box” and achieve the best possible design. The GA tool uses a global optimization method coupled with user-defined merit functions and design constraints.
