[Mesa-users] Regarding MESA tutorial

[Anne Thoul]

Dear Asit,

If you are new to MESA, you might learn a lot by going through the following steps.
For how to build inlists, please see point 2: Using MESA.

Best regards

Anne

Where to find information to install and use MESA

1. Installation:

The very first thing to do is to follow exactly the steps explained on the MESA web site

http://mesa.sourceforge.net/prereqs.html <http://mesa.sourceforge.net/prereqs.html>

One of the first steps involves downloading and installing the mesasdk, maintained by Rich Townsend:
http://www.astro.wisc.edu/~townsend/static.php?ref=mesasdk <http://www.astro.wisc.edu/~townsend/static.php?ref=mesasdk>
Rich’s web page includes a Troubleshooting and FAQ sections for the mesasdk.

In case of problem installing MESA, look at the pages for troubleshooting 
http://mesa.sourceforge.net/troubleshooting.html <http://mesa.sourceforge.net/troubleshooting.html>
and the FAQ
http://mesa.sourceforge.net/faq.html <http://mesa.sourceforge.net/faq.html>

IF you cannot find the answer to your problems in these pages, search the mesa-users list archive. Others may have run into the same problem.
http://mesa.sourceforge.net/troubleshooting.html#search-the-mesa-users-mailing-list-archive <http://mesa.sourceforge.net/troubleshooting.html#search-the-mesa-users-mailing-list-archive>

If you still cannot find the answer to your installation problem, post your question to the mesa-users list.
When you do that, please remember to follow the clear procedure detailed here:
http://mesa.sourceforge.net/troubleshooting.html#search-the-mesa-users-mailing-list-archive <http://mesa.sourceforge.net/troubleshooting.html#search-the-mesa-users-mailing-list-archive>
This tells you which information you need to provide for people to be able to help you.

2. Using MESA

MESA is built to allow users to run experiments in stellar evolution. As such, a lot of freedom is given to the users in terms of choosing parameters and their values. This can be overwhelming when using MESA for the first time.

The first step is to go through the example detailed here:
http://mesa.sourceforge.net/starting.html <http://mesa.sourceforge.net/starting.html>

There are also more examples located in the subdirectory
$MESA_DIR/star/test_suite
There you will find examples closer to the type of star you want to study.
You can use those as starting points for your inlists, and slowly modify them to fit your needs.
Please beware that the examples in the test_suite are not necessarily at the correct resolution, since they need to run fast, and you may need to adjust the resolution to have results that are converged.

The MESA developers are currently working on improving the documentation for those test_suite cases. Coming soon…

Another source of examples is the MESA Marketplace:
http://cococubed.asu.edu/mesa_market/ <http://cococubed.asu.edu/mesa_market/>
There you will find 
inlists used in published papers
MESA Summer School material
Community written guidance on using MESA
Etc…
Finally there is a series of YouTube videos explaining how to use pgstar

> Hello everyone,

> As I am a new MESA user, is there any tutorial to build inlist for a particular project, so that one can get a good grasp on MESA? I know it’s a very naive question but I am little confused on how to use MESA effectively or what are the options available there. Hope to hear from you.
