merging hexa meshes
 

hi all. I'm trying to mesh a channel by blocking. this channel contains two regions. when I mesh these two parts by blocking and try to merge them ICEM says that:
only 2 regions can be merged
currently there > 3 regions
I attached a pic. I accurately specify the size of mesh on the interface.
please help me!

Hi,

ICEM can´t merge hexa/hexa mesh, at least, one of these mesh has to be tetra/tri mesh. Anyway, why don´t you try to do all of this with a blocking?

last time i am able to achieve minimum mesh quality of 0.5....try simple blocking...it's not difficult

thanks a lot.
