Is there any on ho has done transient analysis of I C Engine ombustion. Pleae help I am new to C F D I am using fluent. - Giridhar tech<br />

:This is not the place for that kind of questions, please use the [http://www.cfd-online.com/Forum/main.cgi main discussion forum] for general CFD related questions and the [http://www.cfd-online.com/Forum/fluent.cgi Fluent discussion forum] for questions related to Fluent. --[[User:Jola|Jola]] 03:27, 14 December 2005 (MST)<br />

* As commercial CFD codes become more and more capable, CFD design agencies are more and more pressed to reconsider the cost vs. benefit of developing and maintaing in house codes. I have had many conversations on this topic with other CFD managers and practitioners - there is a lot to think about:<br />
These first few are mine:<br />
1) Competetive advantange - is your homegrown software more capable than software developed by your competitor or available in a commercial CFD code? If I have unique design capability I have an advantage over my competitor.<br />
2) Is commercial software really easier to use? I can apply my code to a new problem faster than I could apply any other code. GUI? who cares! <br />
3) Physical models are generally trivial to institute into a code, commercial or otherwise, unless basic algorithmic and/or data structyure implications are involved (e.g. multiphase flows)<br />
4)The next major leaps in CFD codes are not algorithmic, rather software engineering based. The ultimate code of the future will be object oriented, multi-physics, support unstructured and adaptive and arbitrary polyhedral and overset - everything! Hard for a small CFD design agenct to develop such a tool.<br />
5) Can open source CFD codes and modules play in the future or will ANSYS gobble everyone up and have us all at their mercy?<br />
