TALK=T;RUN(1,1) DISPLAY This run analyses the motion of the lubricating fluid in a journal-bearing,the geometry of which is represented by means of porosities. Interesting variants include: changes to the size and shape of the journal; and changes to the lubricant viscosity. ENDDIS ************************************************************ Group 1.
