I am now doing my project on "Fluid-Structure Interaction study on artery", using ANSYS-9.0, I am doing 3-D FSI analysis using fluid142 & solid185 using FSI solver. I have written a macro as per the help file specified in FSI, ANSYS under coupled field approach.
I tried with time step in terms of milli seconds, i didn't faced any problem with radial deformation of artery, but when time step crosses mili seconds, the deformation is not in radial direction but it's it's predominant in X-direction. can anybody help in overcoming this difficulty ........?
