hello friends..i still have a problem on volume meshing.i draw a small aircraft model and the model will put in the wind tunnel.so i draw the half model of the aircraft, and then create a brick which will be assume as a wind tunnel.the dimension of wind tunnle is (1*1*2.5)M.after creating this two volume, i subtract it in to 1 volume.the problem appeared when i mesh the volume,it said that check the skewness and maybe the face mesh is too big for a small gap..then i shift the position on one part of the aircraft, then, the volume mesh is success..the problem comes again when i try to export to fluent.the error is sound like this: A DEFAULT (UNSPECIFIED) BOUNDARY WAS CREATED ERROR:AN INCORRECT MESH HAS BEEN STORED.CHECK MESH QUALITY BEFORE EXPORT. VOLUME 3 HAS INCORRECT MESH AT FACE FACE63... pls advise

Hi!

It may be helpful if you would split your domain into more than one volume. Instead of substracting the volumes make more smaller volumes with create edge - form face - form volume...

Good luck
