Segmentation Fault

[gkbrkgrr]

Hi,

I am a new WRF user. My current project is modelling the latest Dubai flood but when I run wrf.exe with 20 processors I get the following error:
===================================================================================
= BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
= PID 7992 RUNNING AT havakalite120
= EXIT CODE: 139
= CLEANING UP REMAINING PROCESSES
= YOU CAN IGNORE THE BELOW CLEANUP MESSAGES
===================================================================================
YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Segmentation fault (signal 11)
This typically refers to a problem with your application.
Please see the FAQ page for debugging suggestions

I use ERA5 surface and pressure levels data as input. I attached the namelist and rsl.error files, can you help me please?

My best regards

Hi,
It's unclear what, specifically, is causing the segmentation fault error, but I have a few suggestions.

1) The size of your parent (d01) domain is too small. Domains should always be at least 100x100 grid points.
2) You currently have your time_step set to 162, and while that is 6xDX, you should try setting it to something that will result in integration taking place evenly within an hour. For e.g., you could set it to 150 so that it integrates every 2.5 minutes with no remainder at the final output time.
3) I see that your DX=27km. What type of input data are you using that requires you to need a parent domain with such coarse resolution?
4) Similar to "2)" try setting radt to a value that will create even integration. You could try 20.

您好，请问如何解决这个类似的错误？我在 16 个处理器上运行 wrf.exe，收到以下错误：
===================================================================================
= 您的某个应用程序进程错误终止
= 退出代码：139
= 清理剩余进程
= 您可以忽略以下清理消息
===================================================================================
您的应用程序已终止，并显示退出字符串：分段错误（信号 11）
这通常是指您的应用程序存在问题。
有关调试建议，请参阅 FAQ 页面

我附上了 namelist 和 rsl.error 文件，您能帮我吗？

Since this is a new issue and on a different system can you open a new thread under the WRF subsection.

Include your namelists.wps and namelist.input like you did before but also include all the rsl.error and rsl.out files in a zip folder.
