Dear MFiX user,
We are pleased to announce the MFiX 25.1 release. Please download the latest version. See the release note below that highlights the changes from the previous version.
Please visit the MFS forum for any software related questions, or send administrative questions to vog.eod.lten.xifm@nimda.
Regards,

New features:
- Multi-component diffusion model for the gas phase.
- Diffusion coefficients are set either as constant or using Lennard-Jones model.
- Optional thermal diffusion effects.
- We now solve for (n-1) species equations, i.e. if there are n species, the last species mass fraction is computed as one minus the sum of the (n-1) other species mass fractions.
- Hertzian model for GSP model.
Improvements:
- New format for the GSP config file
gsp_config.csv. - Option to save GSP data as a bounding sphere instead of all component spheres.
- More accurate way to handle DEM damping for polydisperse systems.
- More accurate reporting of elapsed and I/O time.
- Build scripts allow user overriding of module files and parameters, not just functions.
Notable bug fixes:
- Fixed bugs in the GSP convection heat transfer.
- Fixed bug in pressure gradient calculation when using internal surfaces with DEM.
