There is no connection between two geometries in my model. I created the geometries in separate components. How can I join the geometry at the point of contact. Thanks

    Several possibilites:

    • Make 'union' boolean operation for two solids and then split it to get two shared solids => Mesh will be matched automatically
    • Mesh the 1st solid. Make 'emboss' to 2nd solid to get same mesh on contact surface => Mesh 2nd => equivalent nodes
    • Use solver technique to glue  2nd to 1st.

    Thanks for the reply. The contact is between a plate and solid. The top part is a plate so union did not work.

    You make solid mesh with only one element over thickness?

    I was still creating the mesh when I took the screenshot.

    Hi josh,

     

    Before you mesh you need to connect the two surfaces. Try extend surface option. If that doesn't help, please share your model, will take a look at it.

    Please use below FT link.

    Thank you
