Create SPH Mesh (Abaqus)

Create a SPH mesh using existing components in your model.

1. From the menu bar, click Tools > SPH.
   The SPH Meshing Tool opens.
2. Select the component(s) to generate SPH elements for.
   1. Click the components selector.
   2. In the panel area, click comps.
   3. Select the component(s).
   4. Click select.
   5. Click proceed.
   The components you selected are displayed in the Component Name field.
3. Click the Meshing Method field, and select a meshing method.
   • Choose Simple cubic to arrange the SPH particles into groups of 8, with each particle being a corner of a cube.
   • Choose Face centered cubic (FCC) to arrange the SPH particles into groups of 14, forming the corners and the center of each face of a cube.

     This method is similar to a hexagonal close packed (HCP) structure.

   • Choose Node to SPH to manually select a node and convert it into a SPH element.
4. In the Pitch field, enter the distance you would like placed between each SPH element in the component.
   Tip:

   Smaller pitch values will result in the creation of more elements within the same space, whereas, larger pitch values will result in the creation of less elements.

5. In the Material Density field, a density that will be used to generate the material and property.
6. To create a *solid section and *material keyword for each component that you mesh, select the Create Property and Material checkbox.
7. To create a *surface (node based) for each component that you mesh, select the Create surface checkbox.
   HyperMesh uses this surface later for contact definition.
8. In the Selection column, select the checkbox of the component(s) you wish to mesh.
   Note:

   In the Status field, notice the red status boxes. A red status box indicates that the component has not been meshed.

9. Click Mesh.
