Hi,
I have run a case with a symmetric geometry, Therefore, I used the symmetry in the simulation (simulated only half of the geometry) . Is it now possible (and if it is, how can I do it) to mirror the data at the symmetry line so I can see the data for the "whole" geometry? Thanks for the help. Regards, Christian |

Hi Christian,
you can use "Filters->Alphabetical->Reflect" to do this. Best regards Martin |

Dear Martin,
I have done my simulation for single passage of a fan. now I want to read the data for the whole fan. how can I do that, Can you please help me? Thanks for your time, Sivakumar |

Greetings to all!
@Sivakumar: Can you at least specify how much of the fan you have simulated? Otherwise it's nearly impossible to help you... Best regards, Bruno

Dear Bruno,
Thank you for your kind reply, the simulation which I have done is 1/8 th of the fan. As MartinB instruction, I have imported the passage. I am able to import up to 4 Blades with out any problem, when I import further paraView crashes immediately. It is being bit difficult in paraView. it seems the problem occurs due to memory problem, I have 32 Gig RAM and 8 i7 processors. Thanks, Sivakumar |

Hi Sivakumar,
How many cells does your simulated mesh have? And how many times will you have to reflect it? Best regards, Bruno

Dear All
I simulate 20 degree portion of a cylindrical geometry using symmetric boundary with interFoam. I would like to visualize full cylinder in paraFoam. is it possible to do that? How ? thank you in advance |

Greetings Neilson,
A quick test indicates that the "Reflect" filter is limited to using the bounding box limits or the major axis. What this means is that since you have 20 degrees only, then:
You can also select the list of filters that were applied and create a new filter that basically is a combo filter. Problem is that the original geometry will always have to be place in the same place. Best regards, Bruno

I know this is an old post, but it may help people coming across it like me!
The way I mirrored the data (i wanted to now do the simulation 3D from a quasi-3D mesh) was to duplicate the values. The mesh numbering works so that if you take all the internal values into a file internalU and just do: cat internalU internalU > internalU_2 and then include this new file (removing the old values), then the flow field comes out as expected. You have to do this for the boundary patches too. It is a lengthy process, but it is the solution that requires the least thinking or coding. Jack |

Quick answer: There is no simple way to remove it, given that it's showing a slice from the real object, namely the symmetry plane/surface that is present on the original data. The Reflect filter will only created reflection, it will not merge the shared surface.
