My professional career
My name is Miguel Herráez, I am an industrial engineer and Phd in materials science.
From my childhood I have always wished to help everyone and to learn everyday something new to go as far as possible. That is how, a few years ago… I could even work at NASA!
In 2013, I started a Phd and I felt overwhelmed when I realized how many new things I had to master in such a short period of time. I needed to use Abaqus from the very first day, but I did not know anything about it.
I needed to learn quickly, I didn’t know where to get started and I was running out of time. I spent many days and nights reading, filtering and collecting information to get up to date.
Since that time, I have been working with Abaqus daily, for scientific purposes as well as for indutrial projects. This allowed me to develop a unique method to learn how to use Abaqus in an easy and fast way.
Thanks to this methodology, I have achieved further goals than I would have ever expected, and what is more important, I have helped other people to make it real too.

What my students think of my courses
“Thank you, Miguel! It was very detailed and useful, and I found all the answers to all my questions. I had a gap in fracture mechanics, but now I have a wide knowledge that allows me to effectively model the behavior of a composite structure. Thank you very much for your efforts and very good presentation. Looking forward to the next one!”
Hi Miguel, I’ve gone through the subroutines course. This course is perfect for learning subroutines. Big thanks! You put all your efforts into this course. (…) You explained composite damage very well in the UMAT chapter. And my Abaqus skills have improved a lot!
“I have just completed the Simulation of Composite Materials with Abaqus course. I have to say this has been such a great course from the very beginning till the end. Very well presented, explained and structured, combining theory, references, methodology, and practical case studies, with the thinking process capturing the essence of the topic. This course and the knowledge you share makes me want to know even more and dive deeper. I have really enjoyed this course and I am hoping to see more content and courses on composites. I would highly recommend this course. The value and content that is presented in the course saves countless hours of research and struggle"
“Abaqus scripting with Python course prepared me to be industry ready. I learned the automation capabilities of FEA and good coding rules for efficient pre-processing and post-processing. I recommend this course to both young graduates and practicing professionals”
“(…) it is a very useful course to understand the interface with Python and the examples provide very clear guidelines on how to use it in the workflow with Abaqus. Regarding the quizzes, they are very nice to put attention to some key points. A lot of material is covered, and quizzes help in refreshing and settling some topics (…). Finally, I would recommend the course to Abaqus users, because it’s a very good intro to Python scripting and impressive results are achieved even with the student edition of Abaqus“
Learning to interact and automate Abaqus simulations using Python Scripting has really unlocked things I could have never imagined prior to taking up this course. As a structural engineer, I have been using Abaqus for several years, but I always relied on the software graphical user interface (GUI) to run my simulations. This course has completely changed my perspective of Abaqus and has truly unlocked lots of possibilities for me. I'm currently using all my learnings from this course for my research. Dr. Miguel has done a fabulous job in using apt examples to demonstrate how Python scripts can be used to automate tasks, customize simulation workflows, and analyze simulation results. Highly recommended for anyone who uses numerical solvers to tackle complex engineering problems!
“The course Abaqus scripting with Python is very comprehensive and I have benefited from it a lot for the automation of both preprocessing of modeling work and postprocessing the results for my simulations. Thank you, Dr. Miguel, for offering a great course Abaqus scripting with Python. The videos are very detailed explaining each command, and how to efficiently create, edit and reuse it for repetitive tasks starting from modeling, analysis and postprocessing. The access to the course is lifetime enabling me to revisit the website whenever I need to.”
Thank you Miguel, actually, you teach two things at once, Python and Abaqus. Thanks again and again. I am waiting for the simulation of composite materials!!! I will watch the videos again and again […]. A lot of very important steps in building a model in Abaqus/CAE […]. Thanks again!
“By far you have made that anybody can follow the course. You provide all the tools required so that anyone who has ever programmed can follow the course perfectly. Definitely, it is a course made for all levels. I think the course is extremely useful and I would repeat it again for sure. I have felt the course is made taking care of every detail"
“Abaqus/Scripting is a powerful tool to automate any task in Abaqus using Python scripts. This means that it is possible to automate and control any action performed in Abaqus and, consequently, save a tremendous amount of time both in the PreProcess and PostProcess stages. […] I highly recommend this course provided by TecnoDigital School and Miguel Herráez”
“I have just completed the course Abaqus/Scripting with Python and, firstly, I would like to say congratulations. It has been a really interesting course, from which I take lots of resources to implement. I would like you to make new courses with the advanced topics mentioned at the end (optimization, user interfaces…). I hope to see new contributions and courses soon!"
“I have learned a lot from your composite modelling course. My knowledge on FEA has increased a lot after taking your course. Will there be a course on writing subroutines like UMATs?”

Do you have any questions about the course
"User subroutines in Abaqus"?
This course is made of +450 videos (5 to 20 minutes long) which are organized into 13 chapters of contents as detailed above.
All the subroutines developed and lots of additional resources are given next to each of the videos, as well as more documentation and references to go deeper into all the details
Even though user subroutines are considered as one of the most advanced subjects in FEA, we start literally from the ground up.
I have designed the course so that it can be followed without any problem by anybody with basic technical knowledge, with minimum experience in Abaqus or numerical simulations.
I have designed the course so that it can be followed without any problem by anybody with basic technical knowledge, with minimum experience in Abaqus or numerical simulations.
Practical examples of increasing complexity are explained in great detail, step by step, and at the same time covering all the theoretical foundations required to understand it.
If you already have experience with user subroutines applied to FEM, you will find out many new ideas to take even more advantage of them. For instance, combining multiple subroutines in the same models, or putting together Python scripts with subroutines is pretty mind blowing.
Apart from the "programming side", the theoretical background required in every chapter is covered in detail. From Solid Mechanics, Fracture Mechanics, System Dynamics, Finite Elements, and more subjects.

Absolutely!
Abaqus without subroutines is like a smartphone without the "smart".
Yes, you can make voice calls, but you are also missing many more features. No internet, no video calls, no emails, no social media (maybe that's not so bad...).
You get the idea, right?
Being able to control user subroutines in Abaqus involves that we can run outstanding simulations, FE models that would be out of reach otherwise.
So, if you are looking forward to become a Simulation Engineer, the sooner you get familiar with user subroutines, the higher you will reach.

However, I am completely confident that you will love it, more than 100 students in this course and more than 420 user among all my courses proof it.

Yes, you can. That’s what I have done for more than 10 years.
There are too many resources on the Internet, documentation, tutorials, videos… The problem is that you will struggle bringing together all these bits and bytes of information (often incomplete).
Not to mention, this will take you a long time.
That's why in this course I have collected all my experience, and I know very well which are the hardest concepts and most common difficulties.
Anyway, if you don’t take this course, I recommend you (1) count on good learning examples, (2) study the official documentation of Abaqus and (3) work with someone expert in the field to help you clarify the toughest concepts.

Nothing at all, but you will stay stuck in your simulations, spending longer and longer looking for the solution to the next issue that appears in your model.
Otherwise, you will enter this group of professionals who are able to identify and implement the user subroutines required in their simulations in Abaqus.
In addition, since I am working on some extensions for the course, the price will never be lower.
