CFD Online Discussion Forums - [surface handling] select correct patch from surfaceAutoPatch

hello,
when I do surfaceAutoPatch with the geometry I want to patch, I have the issue to separate the patchs I am looking for, the angle in surfaceAutoPatch separates a lot of "patches" that in the simulation are only part of the same, knowing that the desired patches are one in the XZ plane (normal (0,1,0) and point (0,0,0)) the second one in the YZ plane (normal (1,0,0) and point (0,0,0)) and two others in the XY plane with different known points. I know that I can create the new patches from createPatchDict with

Code:

constructFrom patches;

patches (undesired patches);

but how can I select the correct patches to stay? do it manually would be a little bit of trouble as surfaceAutoPatch creates around 120 patches :eek:

best regards, franco
