SPH Generation

Purpose:

This interface is used to generate particles for SPH modeling. Box, Sphere, Cylinder, Cone, and ShellVolume: SPH Mass = Den*Pitch^3 (where Den = User Specified Density).

NOTE: The Fill% option creates a "partial fill" which means filling up the body with MASS (not filling up to a specified volume percentage). So for the SolidNodes method, if the solid mesh is not of constant element size, it may look odd, and the density of the SPH part will not be what has been specified. For all other methods, it will fill up to the given percentage of both mass and volume.

Function:

Sample:

Box

Common controls:

  • Method : Select method to create SPH elements.

  • Clearance : Leave gap between SPH nodes and elements.

  • Fill% : Fill volume level (%).

  • PID : Enter part Id for the unfilled particles (if needed).

  • Den : Enter density of the unfilled portion (if needed).

  • DirX : Set fill direction in X.

  • DirY : Set fill direction in Y.

  • DirZ : Set fill direction in Z.

  • NumX : No. of particles in X direction or radial direction).

  • NumY : No. of particles in Y direction or radial direction).

  • NumZ : No. of particles in Z direction or radial direction).

  • Density : Enter density of the unfilled portion (if needed).

  • Save : Save or replace sph property for each selected part.

  • Start Nd ID : Enter starting node Id for the SPH nodes.

  • Start Part ID : Enter part Id for the SPH part.

Create SPH in Box:

  • PMin : Click to activate Position Interface for min. coordinates.

  • PMax : Click to activate Position Interface for max. coordinates.

  • X : Enter X coordintate for min. or max. coordinate point.

  • Y : Enter Y coordintate for min. or max. coordinate point.

  • Z : Enter Z coordintate for min. or max. coordinate point.

Sphere

Create SPH in Sphere:

  • CenterXYZ : Click to activate Position Interface for center coordinates.

  • CX : Enter X coordintate for center of the sphere.

  • CY : Enter Y coordintate for center of the sphere.

  • CZ : Enter Z coordintate for center of the sphere.

  • R : Enter Radius of the sphere.

Cylinder and Cone

Create SPH in Cylinder or Cone:

  • Position : Activate Position Interface for base point center of cylinder or cone.

  • X : Enter X coordintate for base point of the cylinder or cone.

  • Y : Enter Y coordintate for base point of the cylinder or cone.

  • Z : Enter Z coordintate for base point of the cylinder or cone.

  • Direction : Activate Direction Interface for direction of cylinder.

  • DX : Set direction X with 1 or -1.

  • DY : Set direction Y with 1 or -1.

  • DZ : Set direction Z with 1 or -1.

  • R : Enter radius of cylinder or cone.

  • Len : Enter length of cylinder or cone.

  • R2 : Enter end point radius of cone.

  • Polar : Generate particals in polar coord. system.

Solid Center, Solid Nodes and ShellVolume

Create SPH with Solid Center or Solid Nodes:

  • Del Old Parts : Delete old parts.

  • Use Old PIDs : Use old part ids to create new sph parts.

  • Use Old PIDs : Remove selected part from the list.
