Thanks so much Scott, let me give it a shot next couple of days.  Really appreciate the help

Hi Siyu and Dr. Portillo,

I'm excited to hear you're designing simulations in FLASH! And, I'm sorry to hear you're running into obstacles. I'll see what I can do to help you get back in the fast lane.

Chapter 3 of the user guide (Setting up new problems) is quite detailed, but it may be easy to miss the big picture. In my experience, the simplest way to learn how to make a new simulation is to base it off of one of the included example simulations, which are located in .../source/Simulation/SimulationMain.

My advice is to do two things in parallel: 1) Read through Chapter 3, and 2) Read through the corresponding simulation files of an example related to what you're trying to create. Also, 3) Have a Fortran90 reference handy.

Let's say I want to create a laser-plasma simulation, but I don't know how to start. In this case, I'll look at a related example, the "LaserSlab" simulation (examine the files under .../SimulationMain/LaserSlab). By the time I finish reading Ch. 3, all the while investigating the files of "LaserSlab", I will have the knowledge to make a completely new simulation.

As an example, here's how you could make a modified version of the "LaserSlab" simulation. Copy the .../SimulationMain/LaserSlab directory and its contents into a new subfolder:
(e.g. .../SimulationMain/ScottSlab)

When you're done editing the files, you can build it just like any of the examples, with:
./setup -auto ScottSlab [options]

Let me know how this works! I'll also ask around the Flash Center to see if any basic tutorial currently exists. And, if anyone has already made a tutorial that you'd like to share, let us know!

Best,

Scott

Hi All,

I too am in the same boat as Siyi and would like to add my voce to this request.

Subject: [FLASH-USERS] Request Tutorial

Dear all,
I am Siyi YU, a new user to the code FLASH. I have briefly read the user guide of 500+ pages and have a general idea of the code's functions. Anyway, I am still not sure how to set up a new problem. Is there maybe someone has a simple example to get started easily please?
Best Regards,
Siyi YU
