Tips for beginners

[pedropscf]

Hello people,

I have some professional experience in OpenFOAM and CFD projects and I am trying to learn more about LBM. I have been reading the user guide documentation for a couple of days and there are some thing that are shady to me: how to start a simulation (what kind of command lines I should write in my Ubuntu terminal)? How and where the results from each time step/moment of the simulation are recorded.

Finally, for you that have more experienced with OpenLB, what kinds of tips would you give to yourself (or to a beginner) when you were learning about OpenLB?

Thank you in advance for your time,
Pedro.

Hello Pedro

have a look at chapter 2.1 “Lesson 1: Getting Started – Sketch of Application”, there you will find a description of how to start a program using the example bstep2d. You will immediately see the output on the terminal. Further information on input and output is given in chapter 8 of the User Guide and on visualization in chapter 9.

The User Guide and the provided examples are already a great way to get familiar with OpenLB. It’s also worth taking a look at the Spring School. There is a lab session where an introduction to OpenLB is given. Experienced tutors are also present to provide support and advice.

Let me know if you have any further quetsions.

Cheers,
Jan
