Hello guys,

just a short and probably simple question: I made some changes in the mesh and restarted the calculation. Now Ansys restarts the calculation starting from the last time step of my previous calculation.

How can I clear the results so that Ansys really restarts the calculation starting from time step zero?

Thanks in advance!

(I use Ansys 17.2)

steady-state or transient? Using Workbench?
You can start the transients calculation with -ini-file. That sets the "current timestep" counter to zero.

If you don't need the old results any more, delete the out and res files and the folder that gets created (xxx_001).

Or just start the calculation from the def file in a new empty folder.

Hey Maxim,

I use the workbench and the calculation is steady-state.
If I delete the files .res and .out and start the „solution“ in the workbench the following error shows up:

or in your case it seems that you already have 10 folders (CFX_010).

You could just delete all files except *.cfx (that's the CFX PRE file) and the *.def file (that's the solver file). If you then don't define any initial file/continue from a file, it should start from zero.

Hi,
i guess you can start with again doing "initialize". in this way you can start again same solution set which is after little change
