Question FSI pressure transfer from STAR-CD
 
hello,

which pressure (total or static and relative or absolute) is trasferred from STAR-CD to a structure code? Would the value of the reference pressure value be of importance (other than helping initial computation in STAR-CD)?

thank you

hello

i believe that the star cd transfer the absolute pressure, but i may be not correct.

Thanks JECIL, for swiftly responding. I assume that the COMPUTED dynamic pressure becomes zero when transferring to an impermeable but movable structure. What happens when pressure (WHICH: relative total or absolute total or relative static ...?) is to be trasferred as force component to the wall?

Thanks
