Parameter Estimation
Modeling of flow non-Newtonian fluids using rheological models involves an estimation of number of material parameters from the experiments. The material model parameter values can be calibrated to experimental data using nonlinear least-squares Parameter Estimation techniques. The Parameter Estimation functionality is available under Optimization in the Physics toolbar.
Three optimization solvers are available with the Polymer Flow Module in the Parameter Estimation study step: the derivative-free BOBYQA solver, the gradient-based IPOPT and Levenberg–Marquardt.
