Description (last modified by miha)

Currently DianaSensDAESO only works for specifying the sensitivity problem, but the actual calculation has to be done by some sensitity-capable solver. This should be improved.

Is "sensitity-capable solver" handles lower block triangular structure of the common Jacobi matrix and makes LU decomposition only for the matrix (Fx+alpha*Fx') in the case of the IDA solver?

Sorry, i've removed description somehow.

  • Resolution set to fixed
  • Status changed from assigned to closed

Finally this is done with [5744]. The residuals are calculated in sparse way based on iterators. There could be some improvements possible, exploiting patterns beforehand.

The system works with IDA now, care should be taken about error tolerances.
