I have downloaded openmc via anaconda but it was
shown that dagmc universe is not present,so i dowloaded dagmc in anaconda package . But I am not able to configure openmc with dagmc , so what to do now? should I again install openmc from source? TIA

There are different flavours of openmc 0.14 distributed via conda.

Some contain dagmc while others don’t

To help conda know that you want one with dagmc you can add some details to the conda or mamba install command line.

mamba install -y -c conda-forge “openmc=0.14.0=dagmc*”

conda install -y -c conda-forge “openmc=0.14.0=dagmc*”

I would also recommend doing this in a new environment to minimise potentially conflicts

Thanks for replying, but it is now showing “The following package could not be installed
└─ openmc 0.14.0 dagmc* does not exist (perhaps a typo or a missing channel).”,when i give
input in the command line"mamba install -y -c conda-forge “openmc=0.14.0=dagmc*”,basically my problem is like I cannot connect openmc with the present dagamc, when i had checked openmc version it is said that dagmc support,png support is disabled.
