Since most of these companies can’t afford the resources to develop in-houseThe CFD Pain Survey is found at: codes, then the success of CFD as a design toolhttp://www.o-ptimal.com/survey.html rests squarely on commercial software. Factors such as grid generation, problem setup, and costBest, (to name a few) currently impede the massGreg utilization of commercial CFD software by non- traditional users. (Continued on page 2)
  2. 2. In My Opinion (cont.) LinkedIn CFD Group Manager Kamran Fouladi In the conceptual design stages, one can expect major and frequent changes to the geometry. Grid Phone: generation is a time consuming and labor intensive 610-291-6642 task for simulation of complex configurations and geometry changes can significantly delay the E-Mail:CFDlinked@gmail.com design process. Additionally, commercial CFD flow solvers are developed as general purpose codes and they include numerous options and parameters to set. A user must possess great deal of experience to be able to set up complex problems correctly. This requires fundamental knowledge of CFD and a few days of training just won’t do. Meanwhile, cost might be the biggest issue for most companies to use CFD. Most commercial software are on expensive and annual license purchases, which make them prohibitive to acquire. In short, until the barriers are removed for small to mid-sized companies, CFD will not be used extensively by “the masses” and it would remain a “useful but not necessary” tool.
