Hi Erik,
This is what we are using... I thought it should would be in the latest release
but maybe not (?).
/// getBC returns the boundary condition number associated with {type,entity}
or returns -1 if no bc is specified
inline long getBC(EntityTypeEnum type, int entity)
{ return hasBC(type,entity) ?
long(getTagData(type,entity,tagPrefix(type,BCEntity))) : -1; }
The void pointer is used to store a number of things, from a pointer to user
defined data to integer values for
boundary conditions.
