Creating an initial charge

[david.corbridge]

Hi,

i am following these instructions:

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.
2. Select all the elements of the initial charge.
3. Click (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.

I am using a prt file from Creo for the charge, however when i get to step 4 i am unable to asign an 'initial charge (3D)' that option is simply not available

should i be using an assembly with the final part and charge in the same file?

any guidances on this will be appreciated

Thanks

David

Hello David

Can you please check if you have changed the Molding process to 'Thermoplastic compression molding' or 'Reactive compression molding' on the Home tab - Molding Process Setup.

This will then give you the property option 'Initial charge (3D)' when you select assign property.
