MFiX 23.1 is available for download. This is a major release which adds new capabilities in Procedural STL and a new built-in debug facility for Windows which should make it easier for users on that platform to catch errors in UDF code.
This release also fixes a number of bugs, including a calculation in the particle-wall contact forces which was incorrect for SQP (non-spherical) particles.
All users are encouraged to upgrade.
