These equations when put into Excel or Calc can be solved iteratively (See this help for [ Excel]). The screenshot below shows the three strip heaters (approximated as constant temperature surfaces) surrounded by the aluminum plate and the resulting temperature distribution. Although this is a rudimentary model, it provides an immediate sense of the geometry and gradient in a way that can be easily distributed and modified through OpenOffice.
The file can be downloaded in Open Office format [[Media:2d_Plate_model_3_strips.ods]]or Excel [[Media:2d Plate_model_3_strips.xls]]. Another model was developed for four square heaters which could be used to investigate the design of a modified hot press that used stove element heaters instead of the more specialized Omega heaters and can be found here [[Media:2d Plate_model_3_strips_square.xls]].
