Can someone help me improve my mesh?
 

Hi,

I'm quite new to ansys meshing. I don't know if the insert mesh methods need to be prioritised or.... because I only want to know the surface temperature of the blocks and the liquid distribution inside the liquid box.

The basic structure can be shown in the pictures below. Above the box (liquid zone with inlet and outlet), there are four blocks, inner blocks and outer blocks have different solid materials. Four cylindrical pipes are inserted into those blocks as heaters. In between the block gap, there is a plate and a bended heat pipe. Can someone help me improve the mesh quality?

Thank you!
