I have a beam model of a tunnel cross section, which I run in
TALPA to capture soil interaction during the construction phases.
each structural part (base, walls and roof) is discretized by several beam elements and grouped together afterwards.
I would like to change the stiffness in a few of the beam elements during the construction phases, e.g. the midspan element of the roof slab. However, as
TALPA only allows me to change parameters of groups, and not by individual elements, this doesn’t seem possible?
Is there a clever way around this, rather than grouping each discretized element individually?
This would be a major inconvenience and defeats the whole purpose of grouping elements in the first place.
I’ve tried using secondary groups but
TALPA doesn’t allow that either.
