Hello everybody,

I had a problem with the stress calculation of ahydrodynamicbearing shell. I tried to obtain the stress in thesupporting shelland contact pressure distribution over theantifriction surface ina static study (were I supposed the bearingsupporting only theweight of the shaft) but I obtained twodifferent results for thiscalculation. One of them (that I expectedto be the good one) givethe contact pressure distribution with amaximum in the contactline between the shaft and the bearingsurface, and the other givesthe maximum in other point of thebearing (were initially there wasno contact). I obtained randomlythis two kinds of results (I saythat because I obtained the tworesults by running the study 4 or 5times changing only the positionof the shaft in the assembly toleft it as there was initially)using the SW2007 OfficeProfessional 32 bit running in a P4 @ 3.0GHz and I don't know why,but the worst come right now because wechange the computer (as itwas very slow) to a Pentium Core 2 Quad6600 with the Windows XPx64 to use the SW2007 64 bit also and Icouldn't obtain "thegood result" again.

Could anybody tell me if COSMOS have any limitation inthestudies using Hertz contacts? Does the COSMOS solver supportthiskind of contacts? Why I can't reach "the good result"again withthe 64 bit edition?

Any suggestion will be well received.

Best Regards

P.D.- I attach some pictures of the result so you can seetheexplained problem better.
