    Testing for convergence - residual value

      Hi,

       

      I have been using SW Flow for about 3 months for my thesis. I am wondering if there is a way to input residual value like other softwares e.g ANSYS for convergence using for validation.

       

      It would be appreciated for any input.

       

      Thank you

          Hi Will,

           

          You can't input a dimensionless numerical residual, but we can still manually override the convergence tolerance using the convergence criteria value or percentage which is effectively the same thing.

           

          If you have a study setup you can go to Tools > Flow Simulation > Calculation control options.

          For the particular goal in question you can set the goal criteria to manual and specify a convergence value (with units) or percentage (default is 3% delta).

          The help button will take you to more useful information about the convergence delta criterion values mentioned above so that's the best place to start first!

           

          I hope that helps.


          Thanks,
