You already know how to perform simulations and how to improve your product design? And now you want to learn more about the theory behind the colorful pictures? Then here is the place to be! You can imagine, that the generation of results for the simulation of geometries with a high level of complexity, like round shapes with complex undercuts is difficult. The shear stresses in fluids are analogous to friction forces in solids and can be estimated based on the fluid viscosity. As you can imagine this is not something that is solved easily. All these effects are impossible to calculate exactly with the models that science provides us until today. However, there are very good numerical models which can give us highly accurate approximations of the results with errors being well below 1%.
These techniques are used to help you build better products and reduce the time to market significantly.
