Hi everybody,

I am currently trying to get a deeper insight on Ansys CFX. While I am doing a rather easy multiphase simulation of an aerated labscale water tank I want to acquire some background information.

Is there a book that covers the most common ways how a solver works and what commercial software uses which of these algorithms? So I can get an overview of pros and cons of these softwares.

Another topic is the analysis type: It would be nice if there is some literature that explaines the difference between steady state and transient analysis in Ansys CFX and is quotable at once.

There is a lot of information on this forum, but most of this information is more explanatory. I'd like to have quotable equations (of course also with explanations) and I know that this would be too much for some Thread to handle.

So I appreciate any book recommendations related to the topics above.

P.S.: Obviously I am not a native speaker, so feel free to ask about things that are not clear.

Presumably you have read the appropriate sections in the CFX Theory Guide which comes with CFX? I would guess a fair amount of the details is ANSYS proprietory information and just the top-level stuff is what can be found in CFD textbooks such as An Introduction to Computational Fluid Dynamics: The Finite Volume Method by H. Versteeg and W. Malalasekera etc.

I will check this Book, thanks for the reply!

I got another question:

I am working with an old version of Ansys (14.5), my supervising PhD-Student uses a newer version (18 or something). Does something like a changelog exist?

Kind regards,

Johannes

yes, in the customer portal you can find the changelogs for each version.
Since you are multiple versions behind, I would definitely recommend updating.
