WebbOne practical way to verify that is to monitor the variable which is the main goal of your simulation (e.g. drag force, mean velocity somewhere, etc.) and check how it changes …

Interpreting Residuals: What info can we retrieve for each one?

WebbThe solution in Star-CCM+ is solved using an iterative solver. The solver iterates at each time step until the residuals (i.e., differences between the solution values at each iteration and those at the previous iteration) become smaller than a certain value. The default number of iterations for Star-CCM+ is 1000. WebbIn STAR-CCM+, you can go to your energy solver node, check the box for "Retain Temporary Storage" and step the simulation 1 iteration. This will load your residuals into a field function that you can now use to create a threshold highlighting the highest values (assuming it hasn't already blown up). the golf learning center peoria il https://myagentandrea.com

WebbBy default, the residuals are normalized in STAR-CCM+. Starting from a good initial solution won't decrease the normalized residuals very much. You should switch off the … WebbKeep in mind that the default settings in Star-CCM+ show relative residuals, meaning that they are the ratio of the current residual error to the error near the beginning of the simulation. As such, if using relative residuals, your final "converged" values will be entirely dependent on how good your initial conditions were.
