Who can explain this for me?
 

Dear all,

I cannot understand the following routines:
{

Alloc_Storage_Vars(pDomain,SV_VOF_RG,SV_VOF_G,SV_N ULL);

Scalar_Reconstruction(pDomain, SV_VOF,-1,SV_VOF_RG,NULL);

Scalar_Derivatives(pDomain,SV_VOF,-1,SV_VOF_G,SV_VOF_RG,

Vof_Deriv_Accumulate);

}

I have tried all I can to find any information about this, but failed. Please help me. Thank you.
