Hi everyone

I am starting a thread for the first time and i am an ameteur when it comes to ICEM CFD.

The problem that i have at hand is, conjugate analysis of turbine blade, and have to mesh different zones in the domain. I have started with blocking but it seems like a hectic task to block all the protrusions and holes in the geometry, so moved to tetra meshing. Initially i had problem with holes in the geometry but now i think i have cleared them (as all i could see are only red lines after build topology).

when iam meshing a particular zone, the surface mesh is ok but the volume mesh in that zone is leaking out and not in one point but completely around the surface.

can somebody help me solve the problem?

i am also having the same problem

but my domain is temperature reduction valve

the problem is "There is a leak in the mesh"
There is a leak in the mesh
material ORFN/-1 can reach material fluid.1



thanks in ADVANCE

Hi

I have changed the format in which am importing the geometry. Previously i have used the IGES format. After strenuous efforts with the geometry repair, i have tried importing in Parasolid format and it worked. Now I dont have any leakage in the mesh.

Try importing in Parasolid format.

regards

Prem Chand

i created body after importing,also i created more than one material point for the
same region.

is that right?

thanx in ADVANCE
