Default meshing strategy for tight fit.

Hi.

im using ICEM4CFD as a pre=processor. i'm trying to simulate the flow past a complex object. The object is tightly fitted into a tube. The complex object exsists as an .stl file and the tube a .igs file. i've imported the .stl file and did the segmentation of surfaces and curves, and also imported the tube. after aligning both objects to my desire, i've tried joinging the interfacing surfaces using merge surface tool.

however, the mesh is undesirable. When creating a tube slightly larger than the object, meshing is not a problem and i can easily run a simulation.

Can someone suggest a meshing strategy for tight fitting my object in question into the tube?

thanks

Hi,

We will need to see the mesh you are generating to be able to help you.

thanks mike here is my pic before any attempts on meshing http://www.pbase.com/image/32402615

green is the desired flow domain and grey is the complicated object imported as an .stl. i faced a lot of problems to get the interface of the object and domain to be a tight fit.

i hope this helps
