DEShybrid leads to crash for single and mixed precision versions of OpenFOAM

Summary

OpenFOAM crashes if using the DEShybrid blending scheme with single (SP) or mixed precision (SPDP) compilation.

Steps to reproduce

Compile OpenFOAM in single or mixed precision mode. Run any case with DEShybrid blending scheme for div(phi,U).

Example case

pitzDaily with SA-DDES and DEShybrid blending scheme DEShybrid_pitzDaily.tar.gz

What is the current bug behaviour?

OpenFOAM crashes.

What is the expected correct behavior?

No crash :-)
