Using CYCLIC with mixed element type
Using CYCLIC with mixed element type
(OP)
Hi,everyone
I got a question about the using of command 'CYCLIC'. In my model, there are two types of element,SOLID95 and SHELL93. I used CYCLIC to configue the model as a cyclic symmetric one. But after solution, I found a problem that at the share line of the two elment type, the meshing did not connected, there are two nodes at the same location.
So I wonder whether it is impossible to use CYCLIC with mixed element type.
Thank you !

RE: Using CYCLIC with mixed element type
wait wait wait... CYCLIC does not perform any merging. Merging, glueing or whatsoever must be performed prior to issue the CYCLIC.
I'm about sure it makes no point if there are several types of elements in the cyclic sector, perhaps the only "caveat" is that there should be one cyclic "pair" for each group of elements.
In addition, I suppose you know that DOFs for solid elements and shell elements are not "coherent", shells have 6 DOFs/node whether solids have 3 DOFs/node only, so you must always carefully couple the interface nodes with Constraint Equations. This should not interfere with the functioning of "CYCLIC", because I seem to know that it will build the Duplicate Sector including all what pertains to the Basic Sector.

Thank you for your help. I have found my mistake and succeed in this problem. CYCLIC can be used in fixed element model.
