Switching from Dakota 5.* to Dakota 6.*

Since the release of Dakota 6.0, few modifications have to be made in order to run cases made with Dakota 5.*.

The following changes have to be applied to the to the Dakota input files (for example, dakota_of.in in the Blunt Body case):

• in the first specification block, change the keyword "strategy with "environment";

• in the same block, remove the line "single_method";

• in the specifications block 4 and 5, remove commas from the keyword: change "variables," to "variables and "interface," to "interface".

With these simple but necessary changes, you should be able to run cases made with the previous versions of Dakota smoothly.
