Hi all, <\/p>\n

I have begun the modelling of a heat exchanger, using static structural analysis system. I've read online that hex mesh is preferred over tet, and so fortunately I have managed to apply hex mesh to the majority of the components (some required slicing to do so). However, my tubesheets and baffles [pictured] only appear to agree with the tet mesh ,which I am assuming is either to do with the thinness of the plates or the relatively uneven geometry (corners, holes etc). <\/p>\n

Now my question is: is there any way to force these plates to adopt a hex mesh? And if not, will mixing tet and hex mesh across the various components greatly affect the accuracy of my solution? <\/p>\n

Thank you in advance.<\/p>\n
