XdmfTimeStepsManager

Module responsible for managing XDMF output files and timesteps.

This module handles:

• Writing model data to XDMF format files
• Managing separate XDMF files for fields, markers, velocity and topography
• Converting and formatting data for output
• Coordinating timestep information across output files

The XdmfTimeStepsManager acts as the central coordinator for XDMF output, organizing the writing of different data types to their respective files while maintaining consistent timestep information.
