View TACS Outputs Bug

[sean-engelstad]

• dv1 and other variables don't print out correctly from the TacsInterface sometimes.
• Tried overwriting the dv1 variables again like _updateAssemblerVars call in pytacs writeSolution but that didn't work.
• I know this works in just TACS, so there are ways I can generate the outputs once I get the bdf, dat file (but it won't have the loads).
• One way to fix this is to rewrite the TacsInterface so it uses the pytacs API. That would also allow us to do buckling, steady, and unsteady problems potentially from the same place! Would solve two birds with one stone.
