Where is the source code?

Hello,

I am interested in utilizing PComcot for research purposes. Is the source code still available/free/open to use?

More power!

Hello, thank you for your interest in PCOMCOT. Don't worry, we will upload the source code and the manual very soon, which I think should be next month. A few months ago, we wrote a research article about PCOMCOT and submitted it to a journal.
This article was accepted recently, so I will make all the source code open once our article is available online.

Hello,

Thank you for the response. That is noted.

Congratulations on the success!

Hi, Paul! I have uploaded the source code, examples, and a detailed manual of PCOMCOT.
You can use it whenever you need. Just feel free to ask questions if you have problem using it.

Hello Yifan,

Thank you for the update. Congratulations on the success! I will attempt to compile/install the code very soon. I will keep you posted.

Hello Yifan,

I completely installed PCOMCOT in my PC and in a HPC environment. I attempted to run the modeling in these two platforms with 3 layers. For my PC, the run was successful but it was slower as expected. For the HPC environment, well, there was an error with Bi-CGSTAB algorithm:

ERROR: Bi-CGSTAB algorithm does not converge when solving dispersion term!

The said error was only present in the HPC environment, where I utilized 4 nodes with 16 processes allocated to each.
PCOMCOT_1.txt
Attached is the log file from the HPC environment for your reference.

Thank you so much!

Regards,
Paul

Hi Paul,
I saw that the CFL number of your simulation is too large (2.184), which can cause the simulation to blast out quickly.
You should use a smaller time step or coarser grids to ensure that the CFL number is about 0.5.
Then, you can check if the results are stable with the Matlab scripts.
