The cross-section is modeled with coupled pore-pressure-thermal CPT212 elements:

et,1,212
keyopt,1,3,2     ! Plane strain
keyopt,1,12,1    ! Pressure degree of freedom enabled
keyopt,1,11,1    ! Temperature degree of freedom enabled

The brain cross-section is modeled as a plane strain condition. Temperature degrees of freedom enable the thermal loading effect.
