We are designing the storage ring (synchrotron type) for ILSF. To absorb the synchrotron photons, we use crotch absorber. To get the surface temperature of the absorber with engineering softwares, we first need to know the power dissipated on this absorbers. To do this, I used Synrad software.
Now, my question is, How much should I consider the mesh size (sample/cm) for this facet to properly calculate the lost power (W/cm2) ? Because when I change the mesh size, the amount of this power also varies.
Sorry for the delay, I'm away from the office for a few days.
The total power (per facet) shouldn't change. The rest (power/cell) is a classical binning problem: the smaller cells you choose, the more you sample the peak of the SR power. In reality, the peak of the SR is concentrated on a very small area, so when you use small cells this is nicely "caught". With larger mesh cell size, you average the peak and the neighboring region, therefore you see a smaller value.
The sum (total power) should not vary, so it's simply a question of how you sample the vertical/horizontal SR power function. There is no good answer what to choose as mesh size, it depends on your geometry size, but also on the memory, etc. available, and you do a tradeoff between accuracy and simulation speed.
You should try reducing the cell size on a test facet to very small cells, and see when the peak of the SR doesn't increase anymore. It should give an idea of the real function.
Off: I suggest to update Synrad to the latest (1.4.24) version, it contains several bugfixes.
