Detailed Description

Fixed memory level set data packed in a package. Level set is the signed distance to an interface, here, the surface of a body.

Constructor & Destructor Documentation

◆ LevelSetDataPackage()

SPH::LevelSetDataPackage::LevelSetDataPackage ( )

default constructor, data and address arrays are allocated but not initialized

Member Data Documentation

◆ is_core_pkg_

bool SPH::LevelSetDataPackage::is_core_pkg_

If true, the package is near to zero level set.

◆ near_interface_id_

PackageData<int> SPH::LevelSetDataPackage::near_interface_id_

mark the near interface cells. 0 for zero level set cut cells, -1 and 1 for negative and positive cut cells,
0 can also be for other cells in the region closed by negative and positive cut cells

◆ phi_

PackageData<Real> SPH::LevelSetDataPackage::phi_

the level set or signed distance.

◆ phi_addrs_

PackageDataAddress<Real> SPH::LevelSetDataPackage::phi_addrs_

address for the level set.
