◆ 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_inner inner radius radius_outer outer radius height height pos reference position bottom_wall create bottom boundary side_walls create side boundaries top_wall create 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.
