Hi!

In CFX-Post.

For example when i create a streamline

Geometry..

There is a possible of choice Hybrid or Conservative.

What is the difference between those things?

It is in the help documetation...

1)Search for "streamline" in the help system.

2)Follow the first link...

3)On that page, you will see a section about hybrid and conservative values.

4)In that section it gives a link to another page, as it says to "help you decide" which to use - that page explains exactly what you need to know.

It is well worth your time searching the help system before posting any questions here - it's much quicker for you. I certainly still use it several times each day.

"Tem outro detalhe com análise dedados no CFX 11. Vc tem duas opções: Conservativa e Híbrida. A conservativa vai pegar o valor MÈDIO do Volume de controlo em trono do nó. isto por exmplo, quando vc tenta extrir velocidade da parede com no-slip de condição, dá um resultado diferente de zero!! Errado? ... Não, este é apenas o valor ponderado entre os fluxos que entram e saiem do voluime de controle montado em torno do nó da parede. Se vc fizer o mesmo pelo método híbrido, o valor da velocidade na parede vai ser zero como deveria pela condição de contorno, CFX vai pegar o Valor NODAL. Então cuide deste detalhe, pois os seus resultados podem estar certos e vc não sabe. "

Palavras de um amigo meu!

"It has another detail with analysis dedados in CFX 11. Vc it has two options: Conservativa and Híbrida. The conservativa goes to catch value MÈDIO of the Volume of control in throne of the one in. this for exmplo, when vc try to extrir speed of the wall with in - slip of condition, of the different resulted one of zero! Made a mistake? … Not, this is only the weighed value between the flows that enter and saiem of voluime of control mounted around the one in the one of the wall. If vc to make the same for the hybrid method, the value of the speed in the wall go to be zero as it would have for the contour condition, CFX go to catch Value NODAL. Then it takes care of of this detail, therefore its certain results can be e vc do not know. "

Words of a friend mine!

Nice translation ... BabelFish?

As mentioned in the documentattion: In CFX, the boundary conditions are imposed on the integration points laying on the boundary (not on the boundary nodes). The conservative variable values are actually the results produced by the CFX-Solver. A variable value on a boundary node is not precisely equal to the specified boundary condition and instead, as Rogerio pointed out, it represents the average variable value in the control volume surrounding that node. The hybrid variable values are obtained by taking the results produced by the CFX-Solver and <u>over-writing</u> them on the boundary nodes with the specified boundary conditions

That´s what I said!!!!
