Hello everyone,
I just joined this forum and what better start than to start with a doubt
.
are at grips with the simulation of a bistable with similar behavior to the case presented on ansys: http://www.kxcad.net/ansys/ansys/ansyshelp/coustrutherelecexamp.htmlasel,s,area,1
nsla,s,1 ! thin arm and flexure
nsel,r,loc,x,d8,d8+d4+d5-d6
nsel,r,loc,y,0,d1sf,all,conv,-5,tblk♪
nsel,r,loc,d8,d8+d4
(d3+d7),
♪
mpdata,hf,5,1,22.4,69.3,76.1.80.5,83.7,86.0
mpdata,hf,5,7,87.5
I did not understand how the hf coefficients are calculated.
these coefficients are related to the sf,all,conv,-5,tblk
if lab = conv, value is typically the film coefficient and value2 (below) is typically the bulk temperatures. if value = -n, the film coefficient may be a function of temperature and is determined from the hf property table for material n [MP]. the temperature used to evaluate the film coefficient is usually the average between the bulk and wall temperatures, but may be user-defined for some elements.
come faccio a trovare questi coefficienti??
grazie.
