State-Space model for surface to surface radiation

Please login with a confirmed email address before reporting spam

Hi everyone, I want to use "mphstate" function in Matlab to get the state-space model of my surface to surface radition Comsol model (Coupled soild heat transfer and surface to sureface radiation together). But only ends up with extracting sigular matrices, with all the numbers in the matrices are NaN. Can someone helps me with this? Thanks!
