Hi,

Could some help explain how does one create the right shaped computational domain for complex geometries? From my understanding, there are three types, H grid (basic Square/ Rectangle domain), O grid (Circular Domain) and C grid (a combination of both). However, after divulging in some research I have noticed that many people make their own shaped domain, and don't seem to understand how to do this, and this is primarily for complex geometries such as space capsules. So could someone explain how to create such a domain and then mesh it properly?

Thanks
