Hi All,

The run you gave me went well (Matthias), unfortunately, the level of accuracy
(semi-implicit as it is indirect) isn't enough so I'm currently running
a Multiphysics simulation.

I...

Got it. I've got a decent idea of what you've described so I'll give it a go and see how
the results look.

Just for confirmation, in the ANSYS Workbench (I'm using 14.5), this would look like...

If we wanted an implicit solution then don't we have to use ANSYS Multifield to solve both systems iteratively?
Using the setup you've described will provide me with a explicit solution which might...

Sorry should have been more clear.

I'm running CFX (transient) Fluid Flow and importing the subsequent pressures into a
Transient Structural.

The end goal is to have a 2-Way FSI between the...

Okay, so it turns out I wasn't far off. I didn't have anything wrong with my
expression but the resolution I was getting from my timesteps etc made it
so that the wave wasn't fully observed during...

Apologies, I wrote it wrong the first time Matthias.

Here is my Setup:

Time per run: 1[s]
Timestep: 0.01[s] - I've tried changing it to a timestep of 0.001[s] to no
avail Glenn.

Hi Matthias,

I'm using a time step of 1 [s], with
substeps of 0.1 [s].

Exactly, and in PRE it shows a perfect
sine wave.

Pulsatile Flow Blood Vessel

Hi All,

I'm trying to conduct a 1-Way FSI for a simple blood vessel deformation
in response to a pulse blood flow.

To recreate blood flow, I'm using a inlet expression that forms a sine wave...
