Define Charge in Custom Factory

Mostafa Jafari Gildeh_21173

Hi,

When we have electrostatic force, we can define the particle charge in the factory properties. Does anyone know how can we define charge for a custom factory?

Hi Mostafa,

You would have to create a Custom Property called 'Charge' with 1 element and units of eCharge.

If you have not used custom properties before this tutorial outlines creation of a Geometry custom property in a contact model.

The process would be similar for a factory only defining the property as a Particle property in the Category.

Thanks, But this Tutorial does not work. The Software crashes as soon as I import the contact model.

And If I define charge using custom property, can I use built-in electrostatic body force?

Hi, did you make any changes to the tutorial? I checked it and it runs OK for me with the default settings.

To answer the second question you can combine the in-built and API custom properties, so long as the names and definition of the properties match.

No, I just change input values according to the Manual. But I was able to define charge as the custom property.

Thanks.
