Creating an initial charge

Compression molding analyses require both a part mesh and an initial charge mesh for simulation.

Create a tetrahedral mesh of an appropriate size for the initial charge, and position it in the correct XY location above the part.
  1. Click Select, Viewer toolbar Select.
  2. Select all the elements of the initial charge.
  3. Click Assign (Mesh tab > Properties panel > Assign).
  4. In the Assign Property dialog, click New > Initial charge (3D), or select an initial charge (3D) option if one has already been created to your specifications.
  5. If you are creating a new set of specifications, make the appropriate entries in the Initial charge (3D) dialog.
    Note: If you are using a fiber-filled material, enter the initial fiber orientation values here.
  6. With your selection made, click OK to close the dialog boxes.
The solver will now recognize this mesh as an initial charge, and treat it accordingly.
