only automatic meshing works,

kazra · March 3, 2016, 07:15

hello
im trying to mesh an air to air heat exchanger using multizone meshing method but every time i get an error saying (with all the default values):
Update failed for the Mesh component in Fluid Flow (CFX). Error updating cell Mesh in system Fluid Flow (CFX). View the messages in the Meshing editor for more details.
and in the meshing editor it says:
MultiZone blocking decomposition failed. If you right click on this message, you may be able to "Show problematic geometry" and try a different approach to meshing those bodies.
and also other meshing methods dont work either except automatic one.
i would appreciate any help.
thanks in advance

now im getting a new error saying:
The MultiZone meshing has completed, but no volume elements were created. This may be caused by unsupported circular sweeps.
and:
MultiZone meshing failed during meshing of blocks. Please verify the meshing parameters.
