There is no reason that your element should get called with isw.eq.9 with this input file. You may have a corrupt version of the code. You should probably download a clean version.
The other check you can make is to change the material model to
mate
thermal
fourier isotropic 1
Then rerun with debugging placed in elements/thermal/therm2d.f to see what isw is appearing there. When I do that, I see
ISW = 1
ISW = 26
ISW = 26
ISW = 26
ISW = 26
ISW = 14
ISW = 3
No isw.eq.9 appears. [Test was run in version 8.5]
