21/06/2013 It has occurred to me that the note taking has been rather sparse this month so these paragraphs have been included to try to fill in the work that has been undertaken. More details can be found in the weekly meeting notes.
As models 91-96 were completed the first attempt to match these models up to the Fry list was undertaken. This was not entirely successful and a repeat of this exercise needs to be undertaken with better information on the position of some of items in the Fry list and also their relative location to Ferrous objects.
Attention has been turned to building a substation sub-model. See model notes. An initial model has been built meshed and solved but this model needs further refinement before any results are taken. I will try and update comments on this as I return to this work.
There is some concern over the effect of the vertical gaps in the AISI 1010 plating in the NSW and the SSW. Although ferrous continuity is in principle conserved through the structural steel (H beams) behind the plates, this steel is much thinner and is not of AISI 1010 quality. There is also a question of how good (magnetically) the joins are between the plates and the structural steel. The shield walls are not close to saturation for Step IV, however the difference between the assumed structure of the walls in the hall model and their 'real' structure is a unknown quantity that could have a big impact on the likely validity of the hall model. This unknown needs to be quantified. For this reason I think it is urgent that these differences are understood and I intend to try and model the effect of the gaps in the steel wall to try and ascertain their effect.
