- | =====Checking the convergence of a solution===== | ||
- | One important aspect of numerical simulations is to ensure that the resolution you have chosen to simulate resembles the analytical solution. | ||
- | Generally, the deflection at a point will converge on a consistent solution faster than the stress at a point. | ||
- | |||
- | =====Automated convergence checking script===== | ||
- | The convergence checking process can be automated in SnSScript. | ||
- | [[https:// | ||
- | |||
- | |||
- | * Open your model and run **SnS** on the solid. | ||
- | |||
- | * Run **convergence.rvb** by [[run SnSScript# | ||
- | |||
- | * Next, the script will ask for a point on or in the solid to check. | ||
- | |||
- | * Finally, the script will run (this may take some time) and report whether the solution is converging. | ||
- | |||
- | All of the settings (such as chosen resolutions and the value to check) can be changed in **convergence.rvb** by [[run snsscript# | ||
- | |||
- | If you are interested in the process of convergence checking and why this script was created in this way, check out {{convergencechecking.pdf|this reference on practical convergence checking}}. | ||
- | |||
- | =====Create a convergence plot with SnSScript===== | ||
- | It is also possible to generate a plot of convergence data using SnSScript. | ||
- | |||
- | |||
- | * Open your model and run **SnS** on the solid. | ||
- | |||
- | * Run **PlotConvergence.rvb** by [[run SnSScript# | ||
- | |||
- | * Next, the script will ask for a point on or in the solid to generate the convergence plot. The script will query the von Mises stress and total displacement at this location. | ||
- | |||
- | * The script will run through the various resolutions and write the queried values to the file specified. | ||
