mass caling questions

(OP)
hello,
My riveting analysis with hyperelastic material takes a long time to run in explicit. Going through the manuals about "mass scaling" to reduce the computation time. I just had two questions in which I am not clear from the analysis and examples manual. I have aluminum (density 0.00026 lb/in2 sec4, 6 inches layer) and rubber (density 0.0001 lb/in2sec4, 1 inch layer)in the model. Should one use just one mass scaling factor for both the materials or scale them separately (mesh remaining unifrom)? will this affect the solution? going through the manual there are many options for mass scaling. the fixed one seems the most straightforward to apply. How do you decide the factor to scale your mass without having inretia effects come into play (ensuring quasi static)?
I apologise since some questions might seem basic
thanks a lot
amar
