“Design can be art. Design can be aesthetics. Design is so simple, that's why it is so complicated.”
Paul Rand, 1914-1996
Anyone having seen news of the U.S. must be aware of the turbidity of the campaign to select the next Republican candidate to run for president. Stresses from different candidate orientations have fractured traditional constituencies; some contestants have piled up as well as lost supportive voters in a changing pattern across the nation; then there is the problem of missteps by candidates not choosing their words carefully.
All this mayhem suggests an analogy with the topics in this issue of the Newsletter. You will find an interesting article on stresses that can fracture large protein molecules. There is also an article describing a new modeling program for predicting the piling up or removal of sand caused by undersea turbidity currents changing the structure of the seabed. Finally, problems of missed steps are addressed in the article on Flow over Stepped Spillways.
The good news is that the problems described in all these articles have been nicely answered through simulations with FLOW-3D. If only the political scene could operate so smoothly and easily.
Speaking of smooth and easy, don't overlook the development article on a new user interface soon to be released. Major changes have been implemented based on input from current users. The goal, of course, is to make using our software much simpler and more satisfying to use than trying to decide whom to vote for.
