Hi, I am doing an FS body simulation where the radiator is modeled as a single stl surface- porous rectangular block, which is not aligned with any of the origin planes. The mass flow rate through the radiator is a parameter that i’d like to monitor and optimize, but since the radiator is one merged…

@Naly Yes, that’s exactly what I mean. The ideal workflow would be to create a slice at the inlet point, then add clip filters along the directions to get the size. The area average/integral filter in Paraview can be used to get the value across the complete area. This state can be saved and later u…

Hi @Naly , interesting question! I am tagging my colleague @sjesu_rajendra here. He might give you more information about your issue. All the best, Jousef

Hey Jousef, thanks for tagging me in!! Hello @Naly , Yes, there is a simple solution for your case. Please try to use the STL surface split geometry operation before proceeding to mesh operation. This way you can make assignment to individual faces. Meanwhile, I’m not exactly sure how you would wan…

@jousefm @sjesu_rajendra Hi, thanks for replying I exported each of the radiator block six surfaces from the cad software separately and merged them with the rest of the car. I still can’t select the radiator inlet in the surface result control method, since after the meshing, all porous block su…

Hey @Naly , Thanks for making it clear. By default the mesher groups all faces into one during cellZone creation. These faces can’t be selected to define result control item on. The alternative would be to create a combination of slice and clip filters in order to obtain the inlet face and then infe…

To be clear, you mean clipping parallel to the radiator inlet face, approximating the radiator position in that plane, and approximating further the average velocity on that face from the velocity contours. wouldn’t that be too erroneous for optimization? Is it doable to just create interior type b…
