Select Sensitivity analysis from the UQ study type list to perform a UQ study with a sensitivity analysis.

For the sensitivity analysis method, choose Sobol (the default) or Correlation from the Method list.

For the Sobol method, the most efficient surrogate model is of the polynomial chaos expansion (PCE) type. But you can also use the type Gaussian process (GP). See the Theory sections Surrogate Models — Polynomial Chaos Expansion and Surrogate Models — Gaussian Process. If a GP model is used, you also need to choose a Monte Carlo analysis.
