What is the difference between these three in Ansys 13 Workbench:
- Refresh Project
- Update Project
- Update Design Points

Specifically, which should I click in workbench if...

1. ...if I change an input parameter value and I want to write over the old value?

2. ...if I am exporting DPs (boxes at right in Table of Design Points checked)?

3. ...if I define a new output parameter in CFD-Post, and then I return to Workbench and I want to populate the newly-defined parameter in my Table for all the DPs?

4. ...if I redefine an existing output parameter in CFD-Post, and then I return to Workbench and I want to see the new values of that redefined parameter in my Table for all the DPs?

Do all three of these commands force the solver to re-run in all cases?

Does one of these commands access already-generated info from CFD-Post so that the solver does not have to re-run in order to populate output parameters in the Table of Design Points?
