DEMSLab 5.2 released on May 28, 2023.

• The parallel efficiency is improved by improving the parallel algorithm, especially in situations with a large number of parallel threads (128 or more threads).

• The efficiency of the serial solving has been improved by optimizing the algorithm, with a range of 10-20%.

• The size of data file is reduced by about 20% by using the optimized file storage method.

• The STL file grid simplification tool is added.

• The coupling module between DEMSLab and the popular MBD software RecurDyn is supplied, including decoupling, one-way coupling and two-way coupling. Note that the coupling method is not applicable to flexible bodies of RecurDyn in the current version of DEMSLab.

• The bug with negative particle number after particle breakage using the fast-cutting algorithm is removed.

• The fast-cutting algorithm for breakage is improved to make the calculation more robust.

• The function of converting DEMSLab mesh to STL file has been added.

• The wear calculation algorithm is simplified.

• The function of error reporting and deletion of particles inside the entity has been added.

• A bug during deleting of multi-sphere particle, multi-super-ellipsoid particle, and concave polyhedron particle is removed.

• The User C Function for outputting polyhedral particle information is added.

• Up to 5000 data files can be imported in Video Maker and the number is 2000 files in the old version of DEMSLab.

• Many other small bugs have been fixed.

• This version was released on May 28, 2023.
