hello

i have a problem,i am trying it about one years

is:aeroelastic blade of helicopter with abaqus

i find some method for solution:

1.using abaqus for 2D ANALYSIS of cross section(meshed cross section) and then 1D modal analysis modal,then using ZAERO for aerodynamic load,my problem in case is:linking abaqus and zaero.what is solutin method?

2.using abaqus for 2D ANALYSIS of cross section(meshed cross section) and then 1D modal analysis modal,then writing aerodynamic code ,my problem in case is relating structure with aerodynamic.

by python?or by subrotine(WICH SUBROTINE?)?or by other thing?

3.using abaqus for 2D ANALYSIS of cross section(meshed cross section) for extarcting of material cofficents ,...,and then using result (extracted with 2D analysis with abaqus) in code(writied for structure &AERODYNAMIC LOAD ,??

4.using VABS(http://hifi-comp.com/default.aspx)for 2D ANALYSIS of cross section(meshed cross section) for extarcting of material cofficents ,...,and then using result (extracted with 2D analysis with abaqus) in code(writied for structure &AERODYNAMIC LOAD ,??

3 IS BETTER OR 4?

PLEASE HELP ME,DO I USE ,WICH ONE?1?2?3?4?

PLEASE SAY ME,YOUR EXOERIENCE ABOUT AEROELASTIC OF BLDE.

HELP ME,HELP
