meshing problem with huge and complicated geometry

mirvakili · August 20, 2014, 01:49

Hi every body
I have a big and complicated fixed bed reactor. It has 11 bodies. one body has 3026 parts another one has 4537 parts. workbench meshing couldnt mesh because of lack of memory. ram of my computer is 8 gig and core i3-3220 cpu.
I dont know how I can mesh this geometry. I attached the picture of geometry. can I mesh every bodi lonely? or can I use the symmetry?

your geometry is to big to mesh and it is very difficult to mesh the entire geometry and to get the best mesh quality.
you can use symmetry and try to mesh it in ICEM - CFD which is the advanced version of it.

another possibility, you must reduce the number of nodes and elements, create multiple meshes for different items

I guess this is one of the points where some other meshers (Pointwise?) handle it better.
