ICEM incorrectly setting boundary condition
 

Hi,

I've made a very simple 2D Hexa mesh (*.tin and *.blk files zipped and attached). The PARTS are made so that the base and upstream edges are separate since the first will be a wall and the second will be a symmetry boundary condtion in Fluent. But when I go either to the ICEM boundary conditins or Fluent then the base edges (PART and boundary condition) are combined with the symmetry boundary condition. So I cannot set the Fluent constraints correctly.

Anyone know why ICEM is doing this and how to fix it?

Thanks.

It is the problem of association. un-group curves and reassociate edges to curves and vertex to point.
