Issue with extra_template_inputs in WATTS MCNP plugin

[zaknatnt]

Hello,

I’m trying to use the WATTS MCNP plugin, where I add an extra templated input file to the main input.

Inside the main MCNP input (main.i), I have the following line:

read file=mcnp_template

In WATTS, I configure the plugin like this:
mcnp_plugin = watts.PluginMCNP(
'main.i',
extra_template_inputs=['mcnp_template'],
extra_inputs=[
'tally.i',
'physics.i',
],
executable=exec_mcnp,
show_stdout=True,
show_stderr=True
)
However, I’m encountering an issue — the templated file appears to be missing during execution. The error message is:
Expire parameter is
nonexistent file: mcnp_template

Could you please advise how to correctly include and reference templated input files in this case?

Thank you!

Best regards,
Nataliia

@zaknatnt This was fixed in #109 so we just need to put out a new release that includes that fix. I'll try to get to that today and then once you update your watts package, you should be able to run without issue.
