Path: CubeSat/Thermal
% Generates a 7 node CubeSat thermal matrix The CubeSat has 6 faces and a core node that represents everything else in the CubeSat. * kEdge is a unit conductivity in Watts/mm deg-K * kCore is W/deg-K * x, y, z are the edge lengths in mm. The default node convention is: node = {'+x','+y','+z','-x','-y','-z'}; node 7 is always the core Type CubeSatThermalMatrix for a 3U CubeSat demo. The x faces have the short edges. -------------------------------------------------------------------------- Form: k = CubeSatThermalMatrix( type,kEdge,kCore,node ) -------------------------------------------------------------------------- ------ Inputs ------ type (1,:) 'nU' n may be a fraction, i.e. 1.5 or for a custom CubeSat, enter 3 axes: [x y z], as in [1 2 3] (U) kEdge (1,1) Edge conductivity (W/m/deg-K) kCore (1,1) Conductivity to the core node (W/deg-K) node {1,6} Definitions of node '+x' '-x' etc. *optional ------- Outputs ------- k (7,7) Conductivity matrix --------------------------------------------------------------------------
