test cases mentioned in the book 'the FVM in CFD'

[zhanggh97]

In the book, the FVM in CFD, it says there is a set of basic test cases that can be used to learn how to setup and run problems using the code.

testAdvection.m testDiffusion.m testDiffusion01.m testDiffusion02.m testDiffusion03.m testDiffusion04.m testFlow01.m testFlow02.m testGradients.m testShearRate.m testSmithHutton.m testStepProfile.m testStepProfile2.m testTemperature.m testTransient.m testTurbulence.m

But I didn't find them in tutorals. I wonder where I can find these test cases, especially 'testTurbulence.m'.

Hi, We have updated the tutorials since then. Please refer to the tutorial called flange instead. in the basic tutorials directory. It serves the same purpose as the old testDiffusion case. See also the stepProfile case, it is within the basic tutorials directory as well. Regards

Thank you for your reply. So how about testTurbulence.m? Is there any tutorial for turbulence now?

[mhamadmahdialloush]

We did not include any turbulence in this code.

In the book, chapter5 Exercise 2 Run testDiffusion (which is available as a test case with uFVM) for one iteration, then (a) Use ‘cfdGetCoefficients’ to get the global matrix data structure and compare it to that shown in Fig. 5.18. (b) Use cfdGetMesh to get a reference to the Mesh object and find the definition of a face, a cell and a vertex.

Where can we download testDiffusion case?

[mhamadmahdialloush]

The test cases have been changed since then. Refer please to the case flange in the basic directory in tutorials. This case is a pure diffusion case similar to the testDiffusion case, and it serves the same objective.

So, when the appendix in the book mentions "testTurbulence.m", is it because that test case was actually incomplete and nonfunctional, or because it was working but it was removed? Given how complete and useful for learning uFVM is, it's a real pity that no turbulence support has been added. By doing a search for "turbulence" in the code, I get actually 11 hits, but most of them are case files setting "turbulence" to "off". Don't you have any preliminary implementation of some simple turbulence model in another repository? Thanks a lot!

Hi,

The code provided in the book is an old baseline code, which we never used anymore. Just after the issuance of the book, we started a new uFVM project where we articulated the assembly procedure as well as linear solvers, in a very consistent manner, and that was the main target of the code, to be inline with the relevant book chapters. testTurbulence.m was one of the scripts among the old code, and is not anymore available in uFVM. Sorry for that.

Regards, Mahdi

Yes, I know it's not available in the current version of uFVM, but let me suggest that you provide the old code from some other place, because considering that the purpose of uFVM is to learn, it would be really helpful to take a look at how it was thought to implement turbulence in that old version. You can add it as a wish to the wishlist, if you prefer.
