Recreating Ansys Sim in Abaqus

[Ariana_]

I am trying to recreate a thermal strain problem from Ansys in Abaqus. The original problem is a 2D slice of a hollow cylinder with four different materials with different thermal expansion coefficients. In order to simplify the problem, I created a rectangle in Ansys with two materials that share an edge. I then applied zero x- and z-displacement for all the edges except the bottom, which has zero displacement in all directions. In Ansys mechanical, I am using the default mks unit system and am running a static structural case, and in Abaqus, I am using mm, tonnes, and MPa and am using a coupled temperature displacement simulation. In Abaqus, I recreate the temperature and mechanical boundary conditions and assign the sections to be solid, homogeneous. Despite this being a simple case, I am unable to get the simulations to have similar results. Are there any assumptions that I am missing that differ between the solvers?
