Messages

Messages for all HPC Systems

The new ANSYS Release 2025.R2 has been installed, tested and rolled-out on SuperMUC-NG Phase 1 and CoolMUC-4. ANSYS 2025.R2 has been made the new default ANSYS Release on those systems and the LRZ documentation has been updated in due course.
In case of any related observations, please file an LRZ Service Request. The LRZ download portal for the ANSYS software will be updated with the new ANSYS installation files asap.
It might be worth mentioning, that with ANSYS Release 2025.R2 the Rocky DEM solver is supporting for the first time SuSE Linux Enterprise Server operating system, i.e. SLES 15 SP4,5,6.

The new Siemens PLM Release of StarCCM+ 2025.2.1 (= 2506.0001 = v20.04.008) has been installed, tested and rolled-out on SuperMUC-NG Phase 1 and CoolMUC-4. StarCCM+ 2025.2.1 has been made the new default StarCCM+ Release on those systems and the LRZ documentation has been updated in due course. At the same time the old StarCCM+ versions 2023.x.1, x=1,2,3 have been deprecated and removed from the LRZ HPC systems.
In case of any related observations, please file an LRZ Service Request.
