Hi everyone,

I am currently trying to mesh a turbine blade using ICEM and am running into a problem I can't seem to solve. I'm hoping some of you may be able to shed some light on what is going wrong.

I bring geometry across from my CAD package in .iges format and rename some of the parts so it's easier to keep track of things. I have also been using build topology to merge some stray vertices on a part by part basis. I create two material points, one for the fluid and one for the solid blade.

Following this I go straight to create block using the 3D bounding box option, with some simple associations of the block to my blade passage (vertices etc). However, when I view the pre-mesh, I get problems between the blade surfaces. In this region the cells appear as per the attached image.

Is this an issue with my geometry or have I missed a key step in ICEM?

Thanks in advance for your help,
Neys
