vbslq_f64 and vandq_u64 both require uint64x2_t types as mask arguments, and the Neon intrinsics do not allow for implicit conversion. Fixes build errors with current GCC 11.2.1: /home/abuild/rpmbuild/BUILD/netgen-6.2.2105/libsrc/core/simd_arm64.hpp:171:29: error: cannot convert '__Int64x2_t' to 'uint64x2_t' 171 | return vandq_u64 (a.Data(), b.Data());
Netgen mesh generator
NETGEN is an automatic 3d tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format. The connection to a geometry kernel allows the handling of IGES and STEP files. NETGEN contains modules for mesh optimization and hierarchical mesh refinement. Netgen 6.x supports scripting via a Python interface. Netgen is open source based on the LGPL license. It is available for Unix/Linux, Windows, and OSX.
