problem mesh complicated geometry
 

hi
guys，now i am mesh a very geometry, and i can think that it consists of two parts ,if i mesh the one part separately ,it is quit simple ,but mesh the two part together ,it become too difficult to mesh it。
my question is :
if i mesh the two part separate, what shroud i do ? can i build the two
block and merge them ？

yes you can do it ....

could you tell me how to merge topology of the two block file ?

use sub-topo

How to choose Appropriate element
 

hi
i need to mesh twisted cable(single strand) how to choose appropriate contact element for this structure

What if the nodes at the merging surface of two parts are not the same? Can you explain a litte bit more how to do it using sub-topo? Thank you.
