connectivity of two different 3D mesh components

Hello

you have to do assembly on mesh model but not CAD model because solver do analysis on mesh model

Thanks for your help. Is there any tutorials for assembly of mesh model.

Yes, you can find them in hm help

I am doing analysis of concrete beam reinforced with steel bars. Firstly i did the assembly on CAD software and import it's .igs file in hypermesh. Then i did 3D meshing for both components and assigned different materials and property. But when I apply load on concrete beam load doesn't transfer to reinforced steel bars. Please help me with this.

either the properties are not assigned correctly or there is a connectivity of elements issue. Make sure all the elements are connected at the interface of reinforce and concrete. This may work.
