How to build a model of two blocks without gaps？

[DYLDYLDYL]

Hi!
I wonder how to build a model of two blocks without gaps？My mesh is merged by two mesh files with ICEM.

I want to simulate heat conduction between two blocks. And when I use GapHeatTransfer, it`s not work in this no-gap condition.
When adding Tensor Mechanics, it has gaps between blocks.

I wonder how to creat a whole Heat Conduction and Tensor Mechanics Mesh with tow different materials blocks.

Thanks in advance for your help!

If the nodes on each mesh align you could use the StitchedMeshGenerator to merge the nodes of the two meshes, making them connected for the physics 👍

Thanks a lot ！Your answer solves my problem perfectly ！

Hello

You may want to use ThinLayerHeatTransfer in the connected situation instead of the GapHeatTransfer

Thanks a lot ！ I use the StitchedMeshGenerator, set heat source in block 1, and find heat transfer in block 2. And when adding Tensor Mechanics, it has no gaps between blocks! My problem is solved perfectly!
