Simulate fluids dominated by diffusion and viscous or viscoelastic behavior
With the addition of computational rheology in Simcenter at no extra cost, engineers can now simulate fluids dominated by diffusion and viscous or viscoelastic behavior. Modeling these simulations is possible thanks to the added finite element solver. This method is useful to engineers in consumer product, waste processing, and food and beverage industries who work with mixers, flow containers, slurries, extrusions, and material processing. Simulating rheology accurately is the key to reducing power consumption, emissions and raw material usage while improving product reliability, user experience and liability costs.
You can choose from constitutive laws to model shear-thinning or shear-thickening fluids, viscoelastic and thixotropic constitutive models.
Fitting Rheological Data
Determining the correct model parameters for non-Newtonian models is challenging. With Simcenter rheology modeling, you can import experimental data and the solver finds the best/optimized parameters based on the user choice. The Material Calibration Model is used to adjust model parameters to fit the supplied data.
Center offers a comprehensive suite of models including solvers for free surface, partial fill, viscous energy, film casting, and short fiber. These rheology solvers extend simulation applicability to a whole new category of flow/energy problems and is based on the Finite Element (FE) solver technology to truly model viscoelastic problems.
