re-run analysis after convergence problems

re-run analysis after convergence problems

(OP)
Hi,

I would like to know whether it is possible to re-start analysis after convergence problems (using Ansys 15 APDL).

I am running a material nonlinear analysis and the solution stops at about 70% of the total load.
At this stage, I wanted to change the material properties of few elements to enable the analysis to continue from where it stopped.

I have heard about multiframe analysis and VT accelerator re-run but I dont know how to use them.
If someone can help with the steps (user interface not scripts as I am not good at it).

Thanks so much
