I want to put a Contact on a Delamination simulation but it seems to tell me
"Elements to be separated by cohesive elements are of more than one stiffness number (183 and 172, perhaps more). The CZMESH command is ignored."
I used Ansys as a preprocessor for a simulation in LS-DYNA with cohesive elements and an additional contact. You can try meshing elementwise with standard volume elements (watch out for node numbering) and then reassign the right element type.
Generally mixing cohesive elements and contact should be no problem.
hi I have the same problem the following error message appeared to me
Elements to be separated by cohesive elements are of more than one stiffness number (169 and 172, perhaps more). The CZMESH command is ignored
I am trying to modeling the debonding between concrete and CFRP using 2D analysis. in order to present the debonding I have to use the CZM with contact element. how could I solve this problem could you help me?
after generating the target element and the contact element, I used the following command
TB,CZM,3,1,1,CBDD
TBDATA,1,C1,C2,C3,C4,C5,C6 ( HERE I PUT THE VALUES THAT I CALCULATED FOR (C1,C2,...)
R,1
RMODIF,1,3,-1E6
RMODIF,1,12,-1E6
CZMESH,CM_1,CM_2
after that the error message appear how could I solve this problem (the attached photograph show the model with error mesage
Dear Fatmira,
I haven´t worked in ANSYS for a while now so I can just give you a little checklist....
1) Are the contacts pointing in the right direction? If not, esurf, reverse them.
2) When I mesh my model, I use "line meshing" instead of CZmesh...
3) Is the right material numer adressed to the CZM?
I recommend you to alter an example file to work with your values first and then to alter that command Skript to fit your geometry...
Good Luck!
Greetings, Christoph
P.S: I think I have had the same Error Message when i had refined the mesh the way you did...
Hello Fatmira,
Did you solve your problem? I am modelling the interface between concrete and FRP too. I am using solid65 for concrete, solid45 for FRP and Inter205 for the interface.
Thanks a lot!
