how mwsh a connect cylinder
hi all,
i have a problem with a 3d mesh; i have two volume in my geometry the first is a cylinder and the second is another cylinder when the first is partially connect. i have connect the common face, and now when i'm going to mesh the first don't have problem but the second signal me error if use a cooper mesh. so what i do for mesh this second cylinder if i want mesh with cooper mesh system? thank you for the attention |
*what do you mean with partially connect?
*what's the matter if you delete all the meshes and you try to mesh the second cylinder first? *a picture of your 2 cylinders may help |

according to your schema, B isn't a cylinder.
Anyway, you may split your volume B with a plane (same location as the surface you mentionned). Take care that plane split all the volume, the split operation should give you 2 volumes: a real volume (left from the split-plane) and a annular cylinder (right from split plane). Then for successfull meshing, you have to mesh in this order: cylinder A, annular cylinder, then B cylinder with taking all the right surfaces (already meshed) as source. |
thank you for the answer i will try to do same as you indicate.
i have a another question after the mesh, will i go to connect the volume? if no, are sufficient only two boundary condiction 1 flow in(for cylinder A) and 1 flow out (for anular volume create to split cylinder B) for all volume,that are three now? |
if you did the split as I mentionned, the volumes shoud be connected.
The BC you need to define, are the one for the entire domain (so don't look after subvolumes) |
hi all
i try to do as you indicate, and it is all ok. i have a question if before i split the volume B , after i don't turn out connect the volume B with A. also if i connect the volume A and B after i can't split volume B because the connection is a virtual with a t-junction. |
try to restart from beginning, and just split your volume, with the adequate plane.
Gambit should create 3 connected volumes |
