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. The controlDict dictionary sets input parameters essential for the creation of the database. WebMoreover, we provide the absolute summation of continuity errors in all cell volumes along with the time steps in Figure 16 to further illustrate the consistent results obtained by different methods. Figure 17 compares the iteration number of each linear equation system in L ( 3 ) and L ( 7 ) solved by different methods.
