output restarted solution wrt original initial condition?

[jaredmagnusson]

I'm able to restart tacs and call setInitConditions to specify vars/dvars/ddvars for a Thermoelastic run. However, writeSolution then outputs relative changes to temperatures and deformations with respect to these initial conditions, rather than the true initial conditions that were specified before the restart occured.

This is my workflow:

• running TACS on body for dt=X sec, computing temperatures and deformations, then writing t=X state to file. Output quantities are relative to t=0 state
• after reading in computed t=X temperatures and deformations, running TACS on body for another dt=X sec, and then writing t=2X state to file. However, output quantities are relative to the t=X state, not t=0 state.

Is there a way to fool TACS by setting the inital temperature/deformation state, but then setting writeSolution to write quantities relative to the original t=0 state?

@markleader do you have any ideas on this?
