SDV Naming Conventions #2

Closed sswan closed 9 years ago

sswan commented 9 years ago

Generally, MML tries to mimic Abaqus for UMAT-related tasks. It does not follow Abaqus 6.11 (may be different on more recent versions) in SDV naming. If I define my user material in Abaqus like this:

User Material, Constants=3 1.0, 2.0, 3.0 Depvar 2 1,FOO,definition of foo 2,BAR, definition of bar

The naming of the SDVs in the output database are "SDV_FOO" and "SDV_BAR", not "SDV.FOO" or "SDV.BAR" as is currently implemented in MML. If current versions of Abaqus are like the old version that I'm using can we change the behavior of MML?

I put the dot convention in v3 for all outputs in anticipation of a future enhancement where outputs could be retrieved by attribute look up. I anticipate using it in notebooks, e.g.

plot(mps.Time, mps.S.XX)

Or something like that. If you prefer the underscore separator for SDVs, no problem, feel free to put it back.

I just learned to live with it. For now it doesn't seem inherently better or worse one way or the other. Leaving it alone seems the best option for right now.
