I believe the BSIM model has parameters for self heating. Multisim 10.0 and later include the BSIM 3.3 and 4.5 models. Have a look in the Multisim User Guide (in 10.1 look in Multisim SPICE Reference > Analog Devices > MOSFET for some information on how to specify the parameters.) Documentation for BSIM is on the BSIM website.
