Hi
I want to use setSet in openfoam ver 2.2x but it says
setSet: command not found
Any body has idea ?
Thanks

setSet was replaced with topoSet and works via the topoSetDict.

setSet is still there in 2.2.x!

[mturcios777]

It seems I was mistaken. Apologies for that. topoSet is (in my opinion) a superior tool.

Do you know about the corresponding dicttionary(ies) to run setSet Or topoSet for MRFSimpleFoam (ver 2.1x or 2.2)?

setSet is run in an interactive command line interface. A sample topoSetDict can be found in the $FOAM_UTILITIES/mesh/manipulation/topoSet directory. It shows examples of all possible operations and shows a specific example of creating sets.

I want to run MRFSimpleFoam (ver2.1x or 2.2) for a propeller(MRF sliding mesh) but I coudnt find the dictionaries in this regard. Tutorial is corresponding to mixer2D.
Do you have any comment or source?

[mturcios777]

Its not an MRF case, but the propeller case in $FOAM_TUTORIALS/incompressible/pimpleDyMFoam does a lot of pre-processing that may be similar to what you want.

[reza1980]

Yes,I did AMI implementation already but I have no example to run MRF for 2.1x or 2.2 .I dont think that the toposet dic can be used as general and it must be specific for each case.

You are correct in that assumption. The topoSetDict in the topoSetDict just has examples of all the operations. The propeller case shows a specific implementation. setSet is similar in that the commands you have to enter are specific to your geometry.

If you look at enough cases, you can figure out what you need to do for yours as even though it won't be exactly the same, you may be able to use some of what they do.

Would you please inform me to create the cellzones in MRF It is possible to use 'topoSet -dict system/createAMIFaces.topoSetDict' regarding to define the inner and outter domain as the AMI zones.

It should definitely be possible. My guess is that you would need to repeatedly use the cylinderToCell source, and do some subsets to get inner/outer regions.

I can't really give much other guidance without knowing the type of geometry you want to do.

sphere?!
3D

[mturcios777]

Sorry, I made a correction to my post above. What geometry do you want to simulate in MRF?

[reza1980]

My case is a 3D propeller that is created by pointwise. I made AMI but I have a problem to implement through AMI dur to the tutorial is not related to a propeller(mixer2d) except AMI that it is a propeller case. I need the set up appropriate with my propeller

I did toposet.AMI.create Dic to setup the MRFcells but after load MRFSimpleFoam I faced this error corresponding MRFZones:

--> FOAM FATAL IO ERROR:
wrong token type - expected word, found on line 25 the punctuation token '('

my MRFZones is like below and it seems Ok.
