To add an Uncertainty Quantification study node () to the current study, right-click the main Study node and choose Uncertainty Quantification from the Uncertainty Quantification submenu.

You can also add an Uncertainty Quantification study node to a new study with a study reference to the current study. To do so, right-click the main Study node and choose Add Uncertainty Quantification Study Using Study Reference from the Uncertainty Quantification submenu. The Uncertainty Quantification study node is then added under a new Study node together with a Study Reference node that refers back to the original study. This way, you can set up separate UQ studies with different study types and run them independently and, at the same time, use the original study.

If you have a Study node with a Uncertainty Quantification study node and you want to place the Uncertainty Quantification study node under a new Study node, together with a Study Reference node that refers back to the original study, you can right-click the Uncertainty Quantification study node and choose Move Uncertainty Quantification to New Study.

To add a new type of UQ study and keep most settings in the current Uncertainty Quantification study node, add a new study with a UQ and a study reference to the current study. To do so, right-click the Uncertainty Quantification study node and choose one of the UQ study types from the Add New Uncertainty Quantification Study For submenu. The Uncertainty Quantification study node with the selected UQ study type is then added under a new Study node together with a copy of all the other nodes under the original study. If the original UQ study is Screening, MOAT, you can choose sensitivity analysis, uncertainty propagation, or reliability analysis. If the original study has a Quantities of interest table or Verification quantities of interest table, the newly created UQ study will copy the data in these tables to new tables. If the original study has a trained surrogate function, the newly created UQ study will copy the surrogate function or create a new surrogate function depending on the surrogate model type of the new UQ study. When the new UQ study is computed, new quantities of interest data will be written to the new tables. If Output table group usage is Automatic, the new UQ analysis results will be saved in a newly created Output table group.The newly created UQ study uses Improve and analyze as the Compute action if the original study has a trained surrogate function, such that the new UQ study could reuse the quantities of interest data used to train the surrogate function. Note that, if you want to change the input parameter or quantities of interest from the original study, the quantities of interest data cannot be used for Improve and analyze; instead, use Compute and analyze. Similarly, the newly created UQ study uses Verify only as the Verify action if the original study has a Verification quantities of interest table and a trained surrogate function, such that the new UQ study cannot reuse the verification quantities of interest data from the original study. Note that if you want to change the input parameter or quantities of interest from the original study and create a new surrogate model, the verification quantities of interest data cannot be used for Verify only; instead, use Compute and verify.
