Constructor & Destructor Documentation

◆ ChFsiProblemCylindrical()

chrono::fsi::ChFsiProblemCylindrical::ChFsiProblemCylindrical ( ChSystem sys,
double  spacing 
)

Create a ChFsiProblem object.

No SPH parameters are set.

Member Function Documentation

◆ AddCylindricalContainer()

size_t chrono::fsi::ChFsiProblemCylindrical::AddCylindricalContainer ( double  radius_inner,
double  radius_outer,
double  height,
const ChVector3d pos,
bool  bottom_wall,
bool  side_walls,
bool  top_wall 
)

Add fixed BCE markers, representing a cylindrical annulus container for the computational domain.

Set inner radius to zero to create a cylindrical container. The cylinder is constructed with its axis along the global Z axis. The specified dimensions refer to the interior of the cylindrical annulus.

Parameters
radius_innerinner radius
radius_outerouter radius
heightheight
posreference position
bottom_wallcreate bottom boundary
side_wallscreate side boundaries
top_wallcreate top boundary

◆ Construct()

void chrono::fsi::ChFsiProblemCylindrical::Construct ( double  radius_inner,
double  radius_outer,
double  height,
const ChVector3d pos,
bool  bottom_wall,
double  side_walls 
)

Construct SPH particles and optionally BCE markers in a cylindrical annulus of given dimensions.

Set inner radius to zero to create a cylindrical container. The reference position is the center of the bottom face of the cylinder; in other words, SPH particles are generated above this location and BCE markers for the bottom boundary are generated below this location. If created, the BCE markers for the bottom and side walls are adjacent to the SPH domain.
