Error in Plfotran code

[sahil wani]

Hi everyone,

I am trying to run the GitHub code on our HPC:
https://github.com/Zitong-Huang/PFLOTRAN_H2_Dec_24/

I encountered the following issue while running it.

Could anyone help me resolve this?

The code runs fine on a single core. When I run it on multiple cores, an error occurs due to the output block. If I remove the output block, the code runs without issues.

I need to run the simulation with output files using multiple cores. How can this be resolved?

For reference, the output block used in the input file is shown below.
