Hi, I am currently build a 3D unidirectional fibrous composite RVE in Ansys.

I used type 1 Solid 185 for my both fibre and matrix and adjust the element technology to enhanced strain; while the cohesive element is use INTER205.

After I merge the nodes, I keyed in the command:

TB,CZM,3,,,EXPO

TBDATA,1,TNMAX,GMAX,1000

CZMESH,,,1,x,0

However, a warning "No cohesive element have been created. Please make sure that your input satisfies the cohesive section definition requirements".

I have a problem to apply the cohesive zone between two elements.

Anyone have some idea to create a "curved" cohesive zone between two elements or there are any alternative ways to solve it?

Thank you
