Creating Volume Mesh

There are plenty of free source codes that can create a volume mesh from an STL file. But all of them can do a good job if your surface mesh is healthy without errors such as self-intersecting faces. Here, I'll use Gmsh to create a volume mesh from STL file of cleaned/repaired mesh as explained before in the previous blog entry. Gmsh can crash a lot, but don't blame the software, it's your faulty surface mesh if that happens.

Cleaning/Repairing Surface Mesh

Even though all of this is easily googlable there are countless of options and ways one can pursue to clean their STL file to be later 3D printed or used to create volume mesh for finite element calculations. This is first from the series of blog entries where I'll explain my way of creating and preparing volume meshes. It's easy to create them with plenty of open source codes, but a beginner will likely end up with too high number of elements.

Fluid–Structure Interaction Analysis of Papillary Muscle Forces Using a Comprehensive Mitral Valve Model with 3D Chordal Structure

This work shows the development and validation of the first mitral model that includes subject-specific 3D chordal structure. It has been published in the Annals of Biomedical Engineering. It is first in series of papers that together summarize my work at Dr. Yoganathan's lab in the Department of Biomedical Engineering at Georgia Institute of Technology and Emory University.

Computational Challenges in Cardiovascular Fluid Mechanics

One of the three 2014 Overset Grid Symposium Invited Speakers were Dr. Ajit Yoganathan, the head of the Cardiovascular Fluid Mechanics laboratory at Georgia Institute of Technology. The presentation can be found on the symposium website. The following is the abstract I wrote for Dr. Yoganathan to summarize the talk.

Strongly Coupled Fluid-Structure Interaction Cardiovascular Analysis with the Effect of Peripheral Network

This work summarizes the first two years of my research position in The University of Tokyo. It has been partially published in the Journal of the Institute of Industrial Science, The University of Tokyo, 2011, volume 64, issue 3, pp. 339 – 344. The paper demonstrates strongly coupled 3D FSI analysis with high-order Mooney-Rivlin hyper-elastic material and 1D-0D model incorporating the hematocrit effect.

Assessing Motorcycle Crash-Related Head Injuries Using Finite Element Simulations

This paper is published in the International Journal of Simulation Modelling. It represents my first post-Ph.D. position in Altair Engineering as part of the research network MYMOSA (MotorcYcle and MOtorcyclist SAfety) financed by the 6th Framework Program (Marie Curie Actions) of the European Union.

Numerical simulation of lifted tribrachial n-heptane laminar flames in heated coflow

This work was presented and published in the proceedings of the 6th European Combustion Meeting in Sweden, 2013. It can be argued that this is the most realistic computer simulation mimicking the n-heptane laminar flames in heated coflow. I had been working on this during my post-doc at King Abdullah University of Science and Technology in Saudi Arabia.

Modelling of hydrated soft tissues using hybrid-Trefftz finite elements

My PhD Thesis is complete. This article provides the abstract and the link to download the PDF file of the Thesis. It is the so called provisory version (documento provisório), since the jury might have some suggestions for improvements before the actual defence.

Animation of the response of hydrated soft tissues in Axisymmetry

Set of films (done by OpenGL) with the evolutions of stress, pressure and displacement fields in time. Several different tests are presented, namely confined compression test and unconfined compression tests in axisymmetry.
