CFD predicts Wind loading on the Solar Tracker

Why do we need solar trackers? As we all know solar energy is a green energy. There is a increasing installation of the solar trackers each and every year in Europe. And it is more demanding  growing industry since European

Goodbye Copenhagen, A Shakespearean Epilogue

It’s been a while in since the project started in Copenhagen, and it is perhaps a good time to summarize the adventure so far. Spending almost two month in Copenhagen, Denmark, is enough time to get a good impression of

Answers: Let the Blood Flow!

Here are the answers to last week’s quiz. I hope you liked it – even though I must admit that some answers were quite hard to find. As you see, the highest speed was reached at position (c), in the

Cluster Scale GPGPU with OpenCL

Previous posts about climate modeling and CESM were required as this post is the crème de la crème of CESM from my point of view. Cluster scale GPGPU seems to be very nice, on paper, but as soon as we

Real case simulation of Solar Tracker using CFD

Open Domain simulation A real case dimension of solar panel is considered for the simulation. Since it is an open domain simulation the boundary condition were based on well-posed boundary condition. In that case here in my simulation domain dimensions

Quiz: Let the Blood Flow!

The blood flow in an artery depends strongly on the geometry of the vessel – but can you predict how? In this quiz, I show you three vessel geometries for which we calculated the blood flow. Guess at which positions

Dinosaur racing, two months later

3D model of Argentinosaurus

In a previous post, I presented my project on making a dinosaur racing competition. In that post, I gave some background information about virtual palaeontology, and the purpose of my project here in Edinburgh. If you haven’t read it yet,

As I have already mentioned in earlier posts, my project is Timeline Profiling and Visualisation with Python; so I am actually using too much Python. But why should someone else bother learning Python? Well,there are several reasons! First of all,

Computers detecting the gender

During my project time in Barcelona I have also worked with the company  HertaSecurity on the Gender recognizer application, which is not only a textbook example, but a realistic one. Let me show you  Herta Security Biometric Video Surveillance promotional video:

CESM – Modeling Earth Future Climate

CESM - High Level Component Diagram

Following the previous post, it is clear why climate modeling is performed using computers. The amount of data and computational needs of climate simulations can be significant, so supercomputers are extensively used to perform the task. In fact, THE strongest

Make runtime of your app and life shorter, vectorize!

Vectorization is a first step in optimization process to produce high performance algorithms. Moti and I contended with vectorization for a few days. As mentioned in one of our previous posts, we decided to implement SIMD vectorization using Intel SSE/AVX

The power of Big-Data

Do we really care about the cause ? Big-Data are well into our everyday lives. They change the way we think, act and perceive the world. In the past, humans were trying to explain phenomena by struggling to find causality

A Greek in Edinburgh- PART 2

Well it’s been over a month now,so let me give more perspectives on my experiences here! First of all,everything is still good with work,my flatmates and the weather! Yes, weather is back to usual; now it’s cloudy, in ten minutes

The same pattern re-appears

I find Mandelbrot set very interesting, that is why I have decided to show it to you from the perspective of physicist. Mandelbrot set is named after Benoit Mandelbrot and it is a fractal. Mandelbrot set is the set obtained

Help! The Beatles became XML!

A markup language is a mechanism to add labels to a text to define a structure of the document. The copy editors did that long time ago to give instructions to the typesetters. Now, all these tasks are computerized, and

2nd Copenhagen Quiz

It is now time for the 2nd and last quiz from Copenhagen, dedicated to our final project. If you recall our previous post about climate modeling, it introduced some figures of observed climate data. A precise definition of Albedo can

The Butterfly Effect, Chaos and Climate Modeling

Ever wondered what is the connection between the Butterfly effect, Chaos and Supercomputers? One of the the best ways to describe it can be using climate modeling. Geophysics and Climate Modeling Geophysics is a field in exact sciences that tries to

In the heart of Europe… the sequel!

After a month and a half at Budapest and NIIFI, the training period has ended and we have started producing our own results as planned (see my previous post here). The full training program included many interesting tools; more specifically we

Patching things up

While most Summer of HPC projects involve creating mind-blowing visualisations, the main aim of mine is to edit visualisation software source code. Rather than producing a single impressive visualisation, the outcome will result in easing the process of visualisation for

A patient-specific geometrical model for coronary arteries: introducing Yağmur

In order to perform realistic numerical simulations of the blood flow problem or the fluid-structure interaction problem between the blood and the arterial walls, the geometrical representation of the vascular network has to be as detailed as possible. Within this framework,
