Error : no cross_sections.xml specified in materials

[Nurul Putri Rohmadhani]

Dear all,

Does anyone know what happened with this and what should I do?
I have placed cross_sections.xml in the specified location.

Thx,
Nurul

Nurul,

Without more information on where you placed the cross section file, configured your environment variables, and built the model, finding a fix is difficult. The following pages might help explain how OpenMC looks for the cross section file, and the necessary steps to configure your environment:

• Using and setting cross section environment variable
