Ophelia Mills –
The results section mentions ‘after the simulation’. Can you tell more about what kind of post-processing can be performed to analyze the vessel stresses and displacements in more detail?
MR CFD Support –
For detailed analysis of the vessel stresses and displacements, post-processing tools in ANSYS can be used. This typically involves examining the equivalent (Von Mises) stress and total deformation in the vessel walls. Specifically, users can create stress contour plots to visualize stress distribution and displacement vectors or contour plots for observing the movement of the vessel walls over each time step.

I learned so much from the ‘Blood Vessel (FSI) with the Pulse Velocity’ CFD simulation training. The real-time interaction between blood flow and vessel wall was fascinating. Could you share how the UDF for pulse velocity was applied and executed within the simulation parameters?
MR CFD Support –
Great to hear that you’ve gained valuable insights from our Blood Vessel simulation training. The UDF (User-Defined Function) for pulse velocity was programmed to replicate the pulsatile nature of blood flow within the vessels. This UDF was then read and compiled in ANSYS Fluent, and applied as boundary conditions at the inlet of the vessel to ensure the accuracy of physiological conditions simulated. Executed over the defined time intervals, the UDF dynamically updates the velocity profile in accordance with the specified pulse velocity data.

Is it possible to observe the dynamic deformation of the blood vessel wall in the results, and how does the applied UDF for the pulse velocity affect this deformation?
MR CFD Support –
Yes, the dynamic deformation of the blood vessel wall can be observed in the results from the FSI simulation. The applied UDF for the pulse velocity defines a time-dependent boundary condition that replicates the pulsatile nature of blood flow. This varying inflow creates fluctuations in pressure and shear forces on the vessel walls, leading to their dynamic deformation throughout the cardiac cycle.
Isai Hudson –
I was really intrigued by the FSI simulation of the blood vessel with pulse velocity. It seems like a complex procedure. The review didn’t mention what specific results were observed regarding the stresses and displacement induced in the vessel wall. I’m curious how these factors could potentially influence the overall findings of this project. Could you provide more information on these results and their implications?
MR CFD Support –
The simulation is designed to meticulously capture the interplay between the blood flow and the vessel wall experienced in real-life physiological conditions. As a result of the simulation, stresses and displacements within the vessel wall were thoroughly analyzed to mimic the pulsatile nature of blood circulation. These data contribute significantly to understanding vascular diseases and the mechanical properties of blood vessels under varying blood pressure conditions. This understanding is critical for designing implants, medical devices, and informing surgical procedures. We’re pleased to hear your interest in the intricate details of this FSI simulation and we hope that our solution provides valuable insights for medical and biomechanical research.

Mrs. Maudie Adams V –
I’m fascinated by the dynamic aspect of the blood vessel simulation. Could you explain how the wall displacement due to the pulse velocity is captured in this model?
MR CFD Support –
The wall displacement resulting from pulse velocity in the blood vessel is captured using the Fluid-Solid Interaction (FSI) simulation. In the Ansys Fluent environment, a User-Defined Function (UDF) is written and used to simulate the pulsatile blood flow entering the vessel. The FSI is set up to allow the vessel wall to respond to the pressure and shear stresses exerted by the blood flow. The solver computes the interaction between the blood and vessel wall, leading to wall deformations over time that are synchronized with the pulse velocity.

Dawn Stanton –
I’m impressed with the details provided on the FSI simulation of blood vessel dynamics. Are deformations of the vessel wall during the pulse modeled accurately, and do these deformations affect the flow of blood significantly?
MR CFD Support –
In the simulation, deformations of the blood vessel wall are modeled accurately by considering the proper material properties and boundary conditions reflecting realistic physiological scenarios. The two-way FSI approach allows the deformation of the vessel wall driven by the pulsatile nature of blood flow to affect the fluid dynamics within the vessel. This interaction between structure and fluid can significantly influence the blood flow behavior, which is why FSI models are essential to capture the dynamic nature of cardiovascular biomechanics more realistically.

Ms. Alexa DuBuque –
I’ve watched the results of the simulation, and the vessel deformation was so well-presented. How did you ensure the accuracy of the UDF for the pulse velocity?
MR CFD Support –
Thank you for your compliment! To ensure the accuracy of the UDF (User Defined Function) for the pulse velocity, we first relied on benchmark pulse profiles derived from physiological data. The UDF was then rigorously tested to ensure that the profile of pulse velocity over time matched the expected characteristic of a blood pulse in a vessel. Additionally, iteratively testing and refining our simulation process helped to hone in on an accurate representation.
