Hi,nI am running a two-way FSI simulation of a blood vessel using transient structural and fluent. For my engineering data for transient structural I put in Poisson's ratio and Young's modulus for the vessel wall. However my simulation will not run unless I put in a density for my vessel wall. Is this absolutely necessary? The literature I have read does not cite using a density for the vessel wall, only for the fluid (blood) which I have. Is Young's modulus and Poisson's ratio not enough to run the transient structural simulation?nAlso just in case this information is needed, I put in fixed supports and fluid solid interface on my geometry for Transient Structural.nThanks!n

Transient will need the density because it will be needed for solving mass matrix in the equation:nmore info at:nhttps://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v201/en/ans_str/Hlp_G_STR5.html n-AniketnHow to access Ansys help linksnGuidelines for Posting on Ansys Learning Forumn
