WebThe OpenFOAM solvers begin all runs by setting up a database. The database controls I/O and, since output of data is usually requested at intervals of time during the run, time is an inextricable part of the database.

Meshing is definitely the most critical part of any CFD simulation. The vast majority of the non-converging simulation the reason lies beneath a poor quality mesh or a low-refinement mesh. We proposed many way of analyzing your mesh quality in the past, and they surely remain valid. how to stretch your earsWebBy basic numerical mathematics we know that stop criterions based on residual are affected by the derivative of the non-linear scheme in the zero: if it is not near 1 we have over/under estimation of the error. On the other hand we know that increment-based criterions get worse only when the derivative is near one (but over estimating the error). how to stretch your ears fasterWebTemperatures for convergence criteria jump to 5000 C, way higher than what would make sense.
