Hello!
Simple, I am just wondering if Simulate at the time when solving the matrices, take into account this parameters respecting to material properties.
No. I don't see how it could.
This parameter is only used by the Sheetmetal module (or whatever it's called these days?)
Surface properties can reduce dramatically fatigue strength. Just saying..
Since there is no thickness associated with the surface properties, they can have no reasonable affect.
This is accounted for, to some extent, in the fatigue properties, under the "structural tab" where you can change the surface finish. This affects the S-N curve that Fatigue Advisor generates. You can also enter a "Fatigue strength reduction factor" if there are other surface modifications that affects the fatigue strength in a known way, such as case hardening, shot peening etc.
