I am trying to create a boundary layer on the same face where i did mapped face meshing. When i select my geometry, the inflation definition turns into invalid method. Is there a way to fix this?

Hi Amin,
Here is a screenshot of the error. In the second column under definition, it says invalid method. When i update the mesh, there are no boundary layers created. |

As appear on the pic, you don't select a valid setting.
If you want create an inflation for a body in long a face you must select body in geometry tab and select face or faces in boundary tab! Also if your model is 2d and you want create inflation for a face in long an edge you should select face(s) and edge(s) respectively! |

Amin, When i did inflation with any other type of meshing (instead of mapped face meshing), i was able to. Also, i am selecting the correct body in geometry tab.
I have found some other threads regarding this issue with inflation in mapped faced meshing, but nobody found the correct answer. |

I'm never facing this issue!
![]() Is your model 2D!? Do you try for changing value of other inflation setting? Dear Ravinder! maybe attaching some pics from your model help us for helping you... |

Hi Amin,
Yes, i am working in 2D The project that i am working on is confidential, so it restricts my ability to post any pictures. But if i also created a simple rectangle 2D (pipe) and it has the same issue with putting inflation on mapped face meshing. I appreciate you helping me. |

Oh! Strange!
![]() you're right! if using mapped mesh the inflation suppressed but when suppress mapped mesh the inflation working! This is too weird! I will try to find any solution for this! ![]() |

As I found, in ANSYS Meshing we can not using inflation for mapped meshes!
If you insist that you have a structure mesh with inflation, maybe you can not using mapped (use pave or...) ! Either inflation or mapped! maybe this threat help you http://www.cfd-online.com/Forums/ans...s-meshing.html |

Hi Amin,
Thanks for the help. I figured out that its a default in ansys when it does not allow to do inflation on a mapped face meshing. I tried an alternative way by creating a think surface close to the boundary and doing separate meshing on that surface. IT WORKED Regards |

The thread is rather old, but for those who like me might have had issues with this, I will post an easy solution:
After applying inflation to the entire geometry, insert a new multizone method and then apply the face mashing and voila, problem solved. Hope this helps Mehran |

I am unable to do face meshing here. how can I create a structured mesh in the nozzle surface? though I have made an inflation layer
