Hello, everyone. I encountered an error in a test run. The program aborted.
</p>
<p style="font-family:SimSun;">
I'm using FLASH4.5.

<p style="font-family:SimSun;">
The setup is like:

However, if lrefine_max=2, while the blocks were doubled (nblockx=8,nblocky=6), with all other configurations left unchanged, the error would not show up.

I think it might be a bug. Could anyone help me?
