Hello,

Can someone point me to documentation that explains the solver techniques used in COSMOSMotion 2008? I could not find much in the help section.

Thanks,

Nathan

The FFEPlus solver however is iterative and quite simple: it just guesses at the vector solution, {U} - sticks-in the guess, multiplies by [K] and checks to see if the right side {KU} of the equation equals the left side {F} within some tolerance. It then iterates on the previous guess until the tolerance is reached (I understand users cannot adjust the tolerance). The trick is what guess to use first - that's the proprietary stuff they won't let us see. For example if you have no knowledge of algebra, how to solve the equation such as: 10=5 * U. You'd have to guess, but what "U" do you guess, first to get the answer faster than your competitors? That is the essence of it, at least how I understand it. I have witnesses that COSMOS developer's FFEPlus solver is fastest one out there for some cases (against brand "A"). I hope this helps.
