Thermal Expansion of a hollow sphere

i would like to simulate the thermal expansion (deformation) of a hollow sphere in 3D. My problem is how can i simulate the increased inner radius of the sphere. i have no idea to set a boundary like fixed on the centre of the sphere because ther is no material. So it is difficult for me to set the boundary conditions correctly. i would like to simulate the fraction of the inner radius of the hollow sphere to the new inner radius at higher temperature. Thank you for any help of this problem.
