The new Simcenter FLOEFD 2512 software release as of December 12, 2025 is now available in all its CAD-embedded CFD variants, and also the Simcenter 3D embedded variant. This release delivers focused improvements for fast sealing of geometry for internal flow analyses for all general purpose CFD applications through to multiple enhancements for electronics thermal analysis workflows. Please read on below to explore every new feature grouped under key Simcenter pillars, or scan the topic list on the left hand side to shortcut to the sections that interest you most. <\/p>\n\n\n\n

There are many reasons for performing internal flow CFD simulations depending on modeling application or computational efficiency. For any internal flow scenario, you want to seal geometry as quickly and efficiently as possible

For complex CAD assemblies with hundreds or thousands of parts, this can become a time consuming challenge to make the geometry watertight. You spend your time first, locating gaps and openings, and then sealing them manually with geometry. Such approaches also mean you are making modifications or additions to the CAD model that need to be tracked and removed before you hand back modified product geometry to design and manufacturing teams after you finish your analysis tasks. CFD tools typically have features or utilities to help you. Simcenter FLOEFD users will be familiar with Simcenter FLOEFD\u2019s existing automatic fluid volume recognition strengths and tools such as \u201cleak tracking\u201d to identify paths between faces which is helpful in many instances. 

In Simcenter FLOEFD 2512, a step change in auto-sealing for internal flow CFD tasks has been delivered to engineers in the form of enhancements to \u201cClose Thin Slots\u201d and \u201cFill Thin Slots\u201d. This feature is accessible when you are utilizing\u202fMesh Boolean<\/strong>\u202fapproach to geometry handling and meshing, that is particularly suited to complex assemblies and varying quality found in CAD models. You can now retrieve the internal fluid region automatically for non-watertight models more easily, efficiently, and without altering CAD geometry<\/strong>. <\/p>\n\n\n\n
