## Über den Kurs

Interested in learning how to solve partial differential equations with numerical methods and how to turn them into python codes? This course provides you with a basic introduction how to apply methods like the finite-difference method, the pseudospectral method, the linear and spectral element method to the 1D (or 2D) scalar wave equation. The mathematical derivation of the computational algorithm is accompanied by python codes embedded in Jupyter notebooks. In a unique setup you can see how the mathematical equations are transformed to a computer code and the results visualized. The emphasis is on illustrating the fundamental mathematical ingredients of the various numerical methods (e.g., Taylor series, Fourier series, differentiation, function interpolation, numerical integration) and how they compare. You will be provided with strategies how to ensure your solutions are correct, for example benchmarking with analytical solutions or convergence tests. The mathematical aspects are complemented by a basic introduction to wave physics, discretization, meshes, parallel programming, computing models. The course targets anyone who aims at developing or using numerical methods applied to partial differential equations and is seeking a practical introduction at a basic level. The methodologies discussed are widely used in natural sciences, engineering, as well as economics and other fields....

This is an excellent course. Professor Igel did an excellent job putting this material together. His intimate familiarity and comfort with the material is certainly key to the clear explanation of concepts he provides.The subject material was something I should have learned at a younger age. Those planning to pursue a career in Geophysics will benefit greatly from this course. Many topics are covered in the course, the use of Green's functions is clarified, finite difference methods are derived and illustrated using Taylor series expansions, pseudospectral methods are developed... It was nice to return to uses of Chebyhev polynmials, Lagrange and Legendre polynomials and get a better grasp of their use. The psudospectral section was particularly fascinating since geophysicists routinely use Fourier transforms in their analysis and the applications to simulation provide new insights into their use.There is much to be gained through the course. I suspect it is at an intermediate level and serves as a good foundation for more advanced study. The Jupyter notebooks were excellent and provide an excellent resource for further study and application. They also serve as excellent examples of Python coding of various finite difference and finite element simulations along with applications going beyond this course.

It was the greatest course that I have taken online because it asks you the main ideas through the video, so I only needed to take feel notes on the calculations. I finished it in 9 days and I will definitely recommend to my friends from my former university.

Had a great time learning the concepts of numerical methods and how to apply them using python. This course gave an insight into many real world problems and how their solution can be approached using numerical techniques.

Thank you very much sir.

This is a great course for intro to numerical course with additional bonus on python code, although a little bit too fast pace.

Heiner Igel is an excellent teacher and he stops Just before the real complications begin as he should at this introduction level. The format of the course is such that Heiner Igel explains to the viewer while hand-written equations and drawings appear absolutely synchronized in the background. Then there are programming exercises where you can run simulations in Python (using Jupyter Notebooks). The programs are well-structured and easy to follow and manipulate to test out the theories. Super well prepared - it has clearly taken a very long time to put this course together. The explanations are detailed enough to get a good feel for the numerical methods and their implementations, but not such that everything is painstakingly derived mathematically. Overall a good introduction to numerical methods without too many complications, but you do get a feel for how complicated it could quickly become.

This course teaches me systematically the all kinds of methods to solve the wave-equation of the derivative form. And I want to know the all answers of the tests.

I really enjoyed this course. Concepts are explained simply and the Jupyter notebooks are a lot of fun to play with. One criticism is the few typos found in the course, but they are quite minor. Thanks!

I really enjoyed this course. Professor Igel has done an great job putting all this material together. All concepts are very well explained . The python notebooks are well documented and completes.the theory.

Thanks!

Very good course as an introduction into methods used in solving wave equation numerically. As for me, there were too little maths, especially in the last weeks. Probably it's right, because not everyone is good at it.

Very clear explanations, and visually striking. Python parts well thought out- both in their content, accompanying videos and notebook implementation. Of all the courses I have taken online, this makes the best use of the medium.

This is a great course! It has the perfect amount of theory and practice of seismic wave propagation. I had a lot of fun experimenting with the Python codes and converting them to MATLAB. Thank you for the effort you put into its development, Dr. Igel. Moving forward, I wonder if you planned to develop a similar course for the inverse problem.

Learnt a lot from this course. Very well structured. Some knowledge of seismology, numerical computation is useful. Even otherwise, Prof.Igel does a great job delivering the core concepts of seismic simulation. Would highly recommend to anyone who is interested in numerical modeling of wave propagation.

Incredibly good jupyter notebooks. Very good balance between theory and application. I would have liked to learn about more differential equation than the elastic wave equations and how the methods learned in this course can be applied to other pdes. But then again... "waves" is in the title of the course, so it's not too surprising that waves are the focus of the lecture.

A two thumbs up coarse! I wish it continues!

Thank you Pr. Dr. Heiner Igel

One of the best things about this course is the professor's elegant and lucid explanation of difficult concepts of numerical methods during his scintillating lectures. He is actually aware of his field very well. And the integration of properly commented Jupyter notebooks justified it's name as to "A practical introduction......". Thanks, Professor!!

This course has been an eye opener for me in computational seismology. The concepts and content have been presented in a simple to understand and implement manner. The Jupiter notebooks inclusion in the course were very invaluable. This is a great introduction to seismology. Thank you so much Prof. Igel.
