Goals are still important in a transient solution as you can still monitor them during the calculation. Note that in the above items 2 & 3, I made the assumption that the problem being solved is a steady calculation and not changing with time as transient solution would. Because of the conservative structure of the software, most times this is well before the internal convergence criteria would have stopped the solver, so you save valuable time by defining Goals. And Goals are a great way to indicate that the flow parameters have converged to a certain solution and it is reasonable to finish the solution. The solver could run indefinitely, but at some point the solution is changing very little with successive iterations, so you have to end the calculation. The software itself has some built-in functionality for convergence of the solution, but with Goals it gives the user confidence that their key design criteria are accurate. Initially the Goals will change a good bit, but eventually they will not change as much and will begin to level out to some value. You can track these iterations by monitoring the Goals in both a table and plot. Not the least to mention that while solving the problem, you can view updated values for the Goals in the solution monitor window.īecause the equations governing fluid flow are highly nonlinear, the problem is solved iteratively where the parameters are updated in every computational cell in each solution step. Putting the goal chart to work in the Compare Tool also provides an insightful comparison of results from other projects, where you have either varied the model geometry or a flow parameter. This is great for a visual summary of your project. After solving the problem and reviewing the results, you can very quickly ask the software to view a table of your goals or automatically create one in an Excel spreadsheet. Some examples might include maximum velocity in the Y-direction globally or a component’s average temperature. The main purpose of Goals is to define for the project what are the key design objectives for your simulation. Defines Design Goals and/or other important criteria.The Goals in SOLIDWORKS Flow Simulation serve 3 purposes: My hope in the post is to attempt to clear up any questions that you may have about Goals by breaking it down into 3 sections: first, what is the purpose of using Goals second, what are the different types of Goals and lastly, how to define them. One of the key technologies in SOLIDWORKS Flow Simulation is a concept in the software called Goals.
