At convergence, the following should be satisfied:

• All discrete conservation equations (momentum, energy, etc.) are obeyed in all cells to a specified tolerance OR the solution no longer changes with subsequent iterations.
• Overall mass, momentum, energy, and scalar balances are achieved.
• Monitoring convergence using residual history:
• Generally, a decrease in residuals by three orders of magnitude indicates at least qualitative convergence. At this point, the major flow features should be

For older versions of DAKOTA adopting cases is little bit tricky pursuit, but it's really work.

I am currently the lead of marketing and sales for Flownex Simulation Environment software. In addition to my listed experience I have been accepted to study a modular MBA at UCT Graduate School of Business in 2014.

I have been involved with Flownex Simulation Environment since 2008, initially as a technical design and support engineer. Once I realised my true passion was to develop relationships with clients and intern grow our market, I worked myself up to sales and marketing lead...

LES.
Long. Expensive. Seems to be true.
