Hi,

In the Analyst Tree-contact, what is the measure of the thickness of a cylinder,for example, when the contact is visualized by bondstatus, the thickness of cylinder will change sometimes.

    Hi Raheem,

    Contacts by default are displayed scaled by contact vector, contact between two large particles would be greater than the one between two smaller particles if you have a size distribution.

    There are other contact display attributes which are shown in the help (Display Contact Subsection)

    Hi Stephen,

    That's why I am confused, the contact is bondstatus I defined in the api like Bondv2, but it shows the differnet thickness as figure shows.image

    Hi Raheem, 

    Are the contacts scaled by another value, like Normal Force?  In your screenshot the attribute scaled should be shown just out of sight, above the colour by options.

    Hi Stephen,

    The contacts is the custom property value of m_bondstatus, I only used the m_bondstatusdelta to assign the value. I am trying to debug it. Thanks.

    By the way, when I debugged the code with three particles'(type as "right","middle" and "left") system, for element1.issphere was always false, and element1.type,even without geometry.
