A preliminary 2D model of the plate was developed to allow for a general understanding of the behaviour of the plate which could be made accessible for the community through open office. Using a 2D finite element control volume approach<ref>

~~===Plate Optimization===~~

~~Due to the computational limitations, only the top half of the Kingston Hot press was analyzed in SolidWorks. The components included in the meshing and analysis were the:~~

~~ ~~

~~*Top plate~~

~~*Top gasket~~

~~*Top heaters~~

~~*Top weldment~~

~~ ~~

~~The mesh shown below was generated automatically through the SolidWorks mesh function.~~

~~The thermal analysis carried out through COSMOWorks utilized the following Load/Restraints:~~

~~ ~~

~~*Each strip heater was assumed to be producing 250W of heat at the plate contact. This assumption was based on the pseudo-steady state condition reached by the press after pre-heat, and the fact that the controller acts to regulate the 750W heaters to maintain the setpoint temperature.~~

~~*It was assumed the setpoint temperature was successfully maintained at 150°C at the interface between the heaters and the plate. This is a strong assumption as only one thermocouple is held against the top plate surface at the edge of the plate.~~

~~*It was assumed that the outer walls of the weldment had a convection coefficient of 10W/m<sup>2</sup>K to the ambient air.~~

~~*It was assumed that the outerweldment walls radiated heat energy to the surroundings using a [http://en.wikipedia.org/wiki/View_factor view factor] of 1<ref>~~
