 ### Sample One
 
-For sample one, the die assembly shown in [sample_one_2nd] was used. Thermal and electric contact resistance was simulated on either contact surface with the stainless steel electrodes, which had the geometry shown in [sps_schematic]. The current source was turned on at t = 0, held for 20 minutes, and then turned off. The assembly was then allowed to cool back to ambient temperature (293 K) for another 40 minutes.

 Cincotti compensated for any deviation in properties in the COMSOL model by using the α and β parameters in the contact conductance calculation. These parameters were experimentally derived parameters. This deviation is much less evident in later sample cases, so the parameters were left unchanged for the remainder of the validation study. It is thus important to note that tuning of the current contact model cannot be neglected when accounting for variations in material properties and model parameters with the experimental setup. Benchmarking against a system of interest should be a first step in the process of using the code implemented here.
 
 ### Sample Three
 
 For sample three, the die assembly shown in [sample_three] was used. Thermal and electric contact resistance was simulated on either contact surface with the stainless-steel electrodes, which had the geometry shown in [sps_schematic]. The current source was turned on at t = 0, held for 20 minutes, and then turned off. The assembly was then allowed to cool back to ambient temperature (293 K) for another 40 minutes. A two-dimensional view of the sample three assembly with contact interfaces highlighted is shown in [sample_three_2d].

 Overall, results for both potential and temperature were in good agreement with the COMSOL model and decent agreement with Cincotti experimental data. Both codes had difficulty in the current model with resolving the cool-down period after the current source was turned off. 
 
 ### Sample Four
 
 For sample four, the die assembly shown in [sample_four] was used. Thermal and electric contact resistance was simulated on either contact surface with the stainless-steel electrodes, which had the geometry shown in [sps_schematic]. The current source was turned on at t = 0, held for 10 minutes, and then turned off. The assembly was then allowed to cool back to ambient temperature (293 K) for another 20 minutes.

 The potential results are shown in [sample_four_potential] with the temperature results shown in [sample_four_temperature]. Considering that sample four is the more geometrically “complicated” model under examination here, there are many horizontal surfaces nearby other vertical surfaces (and vice versa). As previously seen in both conducting and non-conducting powders, heat transfer from the surrounding domain is an important part of the SPS process, and some component of that is lost in this formulation.
