Hi all, I'm beginner in Ansys,and have a problem. I want to simulation Thermal stress distribution in optical fiber. Optical fiber consists two concentric glass cylinder, core and cladding. This two regions have same Yang modulus and poisson's ratio, but different thermal expantion coefficients. I don't know,what element must I use for this problem? and how can I introduce surface between core and cladding of fiber?
