Dear answerer, hello. I am running a water - sphere system with 1000 water molecules on LAMMPS【LAMMPS (2 Aug 2023 - Update 3)】
, and I want to calculate its surface tension using the Irving - Kirkwood pressure - tensor method， according to the template on the official website：

{EA0776C6-56F8-4217-AC24-CA313D75B24C}
{EA0776C6-56F8-4217-AC24-CA313D75B24C}808×113 8.54 KB

So I ran the following input file：
{412B6712-3E3C-4574-B5FB-F677DFF74D57}
However, the following errors occurred.
{9C8E0699-6601-487F-BB4A-51F07541532B}
{9C8E0699-6601-487F-BB4A-51F07541532B}801×174 6.2 KB

May I ask how to solve it?

Do not just blindly copy from the documentation, but read and understand it, since there can be typos.

The error message is self-explanatory. Do you have a compute with the compute-id “p”? Apparently not and hence the error.
