Turbofan engine model meshing in gambit
 
1 Attachment(s)
I have created simple turbofan engine model in Gambit, while messing my model i have getting folowing error

"NUMBER OF INTERVALS ON MESHED EDGES OF FACE DOES NOT ALLOW MESHING USING A SCHEME OF MAP"


here i have attached my gambit modle? how and what type of mesing should i have to use?and how can i create inlet and outlet biundary conditions?

You are trying to mesh your surface on the fly with Map, and of course it is not possible.
Split your domain into several mappable subdomains, like this for instance

to create several mappable subdomains, i have to create edges with the corresponding vortex points? are any other method is available to split domain into sevral mappable subdomains?

Split surface with vertex.
you can also split with edges, or with surface (but here you need real entities)

I have created several subdomains as you have shown in the picture.
how to mesh this subdomains? shall i to create each subdomains as a face or a single face to mesh?

all the surfaces should be mappable (quad)

while meshing domain which is not meshed in the figure i am getting the error "NUMBER OF INTERVALS ON MESHED EDGES OF FACE DOES NOT ALLOW MESHING USING A SCHEME OF MAP"


is it correctly meshed the remaining domains?

can u give some example and solution manual for creating, mapping and meshing domains in gambit?

the top sudomain is already meshed with 11 nodes on the lower edge.
Now on the last subdmain you want to mesh, I count 22 nodes on both edges (opposite to the one common with the top meshed subdomain).
Mapp Mesh algorithm isn t able to project the 11 nodes on the 2 other opposites edges, since they are already meshed (with 22 nodes).
So delete all the edges which are not common to meshed subdomains (the 3 lower meshed edges with blue symbols)

ok if i delete the all edges which are not common to meshed domains then how can i mesh the domain?

surface/mesh :)
