Yade

Where to acquire several contact models

Asked by MikeZhao

Hi there,

    On Yade's manual there is a contact model called Ig2_Tetra_Tetra_TTetraSimpleGeom(), but in Yade's trunk ( released on 3.15 ) I didn't find any contact model related to tetra element. I want to know where to get this contact model?

    And would you please tell me whether there is a contact model that can detect contact between facets and calculate internal forces?

    Thank you for your time and patience. And Merry Thanksgiving Day!

I don't understand at all, sorry :-) what happens if you open yade console,
write Ig2_Tetra_Tetra_TTetraSimpleGeom and press enter?

This is not implemented in Yade for "classical" facets. There exists so
called PFacets concept, but I don't know if it is included in public trunk
or not. Let's wait for others' answers :-)

I see, there is the Ig2_Tetra_Tetra_TTetraSimpleGeom() contact model somewhere in the program, however it's not in an isolated file, and that the reason why I didn't find it.. I just planned to see how was the contact model built in detail..

Thank you again for your quick response, and have a nice day!

Ok, now I understand. The source code is in yade/pk/dem/Tetra.*pp
