Hi,
According to the user manual, by default, dissipated energy by friction (*GAP HEAT GENERATION) completely is converted to heat (η, fraction of dissipated energy converted into heat, η=1), and again by default, the heat is distributed equally between the two surfaces, f=0.5.
In my case, i would like to change the f=0.1, so 10% of the dissipated energy is going to be in the internal heat energy of the slave part. To make sure about it, i created test case. I make the friction induced heat generation is the only heat source (I also tested this by making fraction of dissipated energy converted into heat, η=0, and it is validated), I will proceed figure by figure,
In figure 1, Internal heat energy increase of the entire model is identical with the friction dissipation. This proves fraction of dissipated energy converted into heat, η=1, and only heat source in the system is friction.
In figure 2,
Internal Heat Energy increase of the each part and whole model is given with (0.9)*(Whole Model Friction Dissipation Energy) and (0.1)*(Whole Model Friction Dissipation Energy), as you can see they are not matching, in other words,
(0.9)*(Whole Model Friction Dissipation Energy) ≠ Internal heat energy increase of the Master Part, and
(0.1)*(Whole Model Friction Dissipation Energy) ≠ Internal heat energy increase of the Slave Part.
Then i run the simulation with f=0.0, so in this case internal heat energy increase in the slave surface should be 0, but it is not, shown in figure 3.
My question is, what is the reason of this inconsistency between manual and my application, am i missing something ? and How can i properly distribute frictional dissipation energy to surface in different ratios?
Thank you for your time.
