TALK=T;RUN(1,1) PHOTON USE p;;; msg Temperature contours con tem1 z m fi;0.001; con tem1 y m fi;0.001 con tem1 x m fi;0.001 msg msg Press e to END ENDUSE DISPLAY This modification of Library case 100 exemplifies the use of the Linear Temperature Link. Linear Temperature link allows 'pipe-like' heat transfer by providing sub-grid-scale links within the computational domain. If there are thermal leads, thermal bridges or thin metal plates embedded in a poorly-conducting medium that would prevent use of coarse grid, this feature can directly link originating and destination cells. enddis ************************************************************ Group 1.
