rigidBodyMeshMotion accesses CofG even if CofG object not specified
Summary
rigidBodyMeshMotion saves the CofG of even if not needed. This causes problems whilst checking for whether the body supplying the CofG is actually valid.
Steps to reproduce
multiphase/overInterDyMFoam/boatAndPropeller tutorial
What is the current bug behaviour?
Out-of-bounds access if bodyId of CofG is negative.
Environment information
- OpenFOAM version : v2103
Possible fixes
do not access rigidBodyMeshMotion::bodyIdCofG_ unless needed.
