Modal Analysis of a pipe with coolant in it .(Fluid and Structure interaction in Optistruct)

Anubhav

I have modelled pipe with Shell elements and coolant with tetra element .

I have to perform modal analysis .

I have used MAT10 property for fluid .

How to model the fluid pipe interaction .
As the pipe system has horizontal and vertical pipes .

Hi,

for modeling fluid-structure interaction in OS with fluid explicitly modeled you have to define ACMODL card .

You can also check out this article for more details:
