1 Switching from Dakota 5.* to Dakota 6.0.0

Since the release of Dakota 6.0.0, few modifications have to be made in order to run cases made with Dakota 5.*.

The following changes have to be applied to Dakota 5.* 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.

2 Switching from Dakota 6.0.0 to Dakota 6.1.0

The following changes have to be applied to Dakota 6.0.0 input files (for example, dakota_of.in in the Blunt Body case) in order to use them with Dakota 6.1.0:

In the interface block change the template_directory keyword to copy_files as follows:

• In version 6.0.0 you do like this,

              template_directory = 'templatedir'

• In version 6.1.0 you should do like this,

              copy_files = 'templatedir/*'

The rest of the input file remains unchanged.
