FISH Function for Getting/Setting Joint Plane Contact Extra in 3DEC

[Mahdi.S]

Hi everyone,

Does anyone know the appropriate FISH function to get/set the “extra” values for Joint Plane contacts in 3DEC?

This data can be visualized in the plot as “Joint Plane Contact Extra”, but I can’t find a corresponding FISH function for accessing it.

I’m aware of the following functions:

• block.contact.extra
• block.subcontact.extra
• block.face.extra
• block.gp.extra
• block.zone.extra

However, none of these seem to correspond to the joint plane contact extras.

Any guidance would be appreciated!

Hi!

block.contact.extra and block.subcontact.extra are indeed what you are looking for.

Running the small script below:

model new

block create brick test
block cut joint-set
block zone gen edgelength 0.5

fish define set_extra
    loop foreach local cpnt block.contact.list
        block.contact.extra(cpnt, 1) = math.mag(block.contact.pos(cpnt))
        loop foreach local cxpnt block.contact.subcontactlist(cpnt)
            block.subcontact.extra(cxpnt, 1) = math.mag(block.subcontact.pos(cxpnt))
        end_loop
    end_loop
end

[set_extra]

Gives you the following contours for contact and subcontact extras, respectively.

Cheers!
