Hey,
Is there anyone who knows how to create an interface using two boundary faces? These two faces have different shapes and areas. Thanks. Last edited by famerfamer; July 23, 2011 at 21:48. |

Just mark both boundaries, right-click and choose "create interface". It doesn't matter whether they have different shapes and sizes. The interface will be created only in the common area. So both boundaries should share some areas (except for periodic interfaces).

Use merge/imprint or the Surface wrapper

Hello,
first you have to combine both surfaces in part level, then right click on repair surfaces, change the option merge/imprint, select one of the part as source and the other as destination, then click Merge/imprint with a tolerance of 0.1mm. that will create a surface that will intersect both parts and will define the shape of the future interface. click ok and now split the part that you combine before with rigth click and split surface by topology. now you have to select all parts and to create with right click new regions, select create interfaces and one region per part, it will atomatically create a new interface with between the diferent size parts. ---------------------------------------------- Another option is that first you first as well in the part level, select the two parts and with rigth click select find part/part contact. then give a tolerance of 0.1mm. When you create the new region, automatically it will create a interface between both regions. with this, you have to use the surface wrapper, and the results are very good. Have a nice day, Emaurici |

Abdul is correct - it is that simple - even if both regions have only one boundary surface.
You only need to go through the imprint process described by Emaurici if you want conformal surface matching - this also enables automatic interface detection at Region creation time. |

However, I think only common areas should be highlighted because, like you mentioned, only this area is the interface I want. |

please read the Help on interfaces and imprinting - it is all explained. The only difference between a conformal and non-conformal is in the way you have prepared your CAD - if the two surfaces have coincident boundary edges then they are conformal, otherwise they are not, and STAR-CCM+ does not really care - the mesher simply splits the surfaces itself. Adding 'thin' surfaces in SolidWorks is wrong - if you want conformal surfaces, then use the surface split feature in SolidWorks or use Imprinting in STAR-CCM+
