Themal conductivity as a Heaviside Function

Please login with a confirmed email address before reporting spam

Hi. I am a new user to COMSOL Multiphysics and I'm using COMSOL 4.4 version. I'm trying write a variable thermal conductivity as a Heaviside function. The expression is: 0.27+0.18x10^-2T; T<100 degC & 0.21; T>100 degC. Please suggests me how to write the expression in comsol & in which option I shall write it.

Thanks
