WB 19.2 Bolt Tool - Gives working load as max, min and total.What does the total column mean?

[acrmnsm]

This is new and I cannot find anything in the help or documentation.
Using the bolt tool - we have applied a preload to the bolt, (its 3d, don't ask).
So then we apply in steps a load to separate the flange - and we get the working load results. So far so good, but I have no idea what the total column is? It is approx 150 x the working load.

How many bolts are there in the assembly?

 

[acrmnsm]

Just one. Its a 2degree slice of the flange, and sliced down the middle of the bolt, with frictionless (symmetry) - however it would be 90 bolts. I considered that perhaps it was multiplying up on my behalf, but is 320 times bigger.

In linear analyses with no symmetry boundary conditions the total is simply the sum of all the
working loads. Are you using rotational symmetry? Can you share a few pictures of the model?

 

[acrmnsm]

Apologies - edited, its a 4 degree slice of a flange with frictionless supports at the symmetry slice faces. I can not share the images as work have a strict nothing leaves the building policy.

Is the first load step bolt pretension?

Id model the section like in this example (one whole bolt
inside the section).

Yeah first step is pretension, but as per the graph above that does not seem to ramp up until the 2nd step anyway, which is when I started applying my external load to open the flange. This is 19.2, in older versions there is not the Total column.
