[petsc-users] Error calling TSSolve more than once with TSSetSaveTrajectory

[Salazar De Troya, Miguel]

Hello,

If I set up my TS with TSSetSaveTrajectory() and then call TSSolve() more than once, the second time I get this error:

[0] TSSolve() line 4102 in /Users/salazardetro1/scicomp_libraries/firedrake-debug/firedrake/src/petsc/src/ts/interface/ts.c
[0] TSTrajectorySet() line 73 in /Users/salazardetro1/scicomp_libraries/firedrake-debug/firedrake/src/petsc/src/ts/trajectory/interface/traj.c
[0] TSHistoryUpdate() line 82 in /Users/salazardetro1/scicomp_libraries/firedrake-debug/firedrake/src/petsc/src/ts/interface/tshistory.c
[0] Petsc has generated inconsistent data
[0] History id should be unique

If I call TSAdjointSolve() in between calls to TSSolve(), there is no problem. Is this the intended behavior for TSSetSaveTrajectory? Meaning that TSAdjointSolve() always has to be called right after TSSolve() if TSSetSaveTrajectory() is called. I need to call TSSolve() independently of TSAdjointSolve() whenever I want to perform a line search during the optimization.

Is there a workaround like creating a new trajectory whenever TSSolve() is called?

Thanks
Miguel
