CFD Solver Memory & Runtime Calculator How much RAM a case needs, whether it fits the node you have, how many cells per core that leaves you, what Amdahl's law says about the speed-up and why it is the wrong question, how long the run takes and how much disk the transient output will eat. Every per-cell memory figure is attributed to published vendor guidance and given as a range. Grid Convergence Index (GCI) Calculator Three grids, three solutions, and the number a reviewer asks for: the observed order of convergence, the Richardson-extrapolated value and the fine-grid GCI, with the transcendental order equation solved properly rather than approximated, oscillatory and diverging cases detected and refused, and the ratio usually sold as an asymptotic-range check shown for what it is.
