After that, I clicked on File -> Merge and selected the Interactive_Elasticity.pro file. Here comes the problem. The instruction writes: “You will be prompted to setup your material, sources and the boundary conditions for each physical group, interactively.”. You can see from the attached screenshot (using the latest Linux x64 binary of ONELAB) that only the boundary conditions appeared.
You just need to define a physical group for the surface as well.
