ACIS error 20000, GAMBIT
 
Hi I am comtinuously getting an acis error 20000 whenever i try to create a face using wireframe in geometry. It says the wireframe contains edges that cannot be connected. Could someone please tell me how to identify these errors so that i can correct them. Thank You

Edges are disconnected i.e. at some boundary two edges are not having one common vertex.

Thank you Far for the quick response. Unfortunately I have one more question. I solved that issue but after meshing the geometry i am not getting a smoother mesh and fluent does not accept it. So how can I make a smoother mesh. I used the tool to smooth the mesh but its still irregular.

what do you mean by smoother mesh. Fluent should accept the mesh no matter how irregular it is. Please post some images of mesh, so that we can help you.

These are the image links.
There should not be any meshing inside the entities in the middle of the room simulating an occupant but gambit still keeps on meshing those 3 entities.

your method of creating the topology is not correct. In other words, faces are not created in proper way. Can you attach dbs file

pratik c February 12, 2012 07:39

The dbs file size is 7mb so could you please provide me with your email adress. So that I can send it to you. Thank you.

Made very quick attempt. Although it is very rough, but you should be able to get the idea that What I am trying to explain.

Meshing is done?
