If you truly have zero budget, do not resort to cracks. Use legitimate open-source CFD tools. They have a learning curve but are powerful, validated, and safe.
In plain English: V12 introduced a new matrix pre‑conditioner that was supposed to speed up convergence for highly skewed meshes. Unfortunately, the pre‑conditioner’s scaling factor was mis‑calculated for cells whose size ratio crossed a threshold. The result is a that crashes the linear solver—a classic “crack” that manifests as a hard abort or a silent divergence. Key features of version 12 include: Engineers, researchers,
