5.5.3. Starting an Evolution or Time-Dependent Calculation from Existing Results and Restart Files

As described in Starting an Ansys Polyflow Calculation from an Existing Results File, you can have Ansys Polyflow start the calculation using an existing results file as an initial solution. For an evolution or time-dependent calculation, you will also need the value of or for the given results. This information is provided in an additional file, called the restart file, which is automatically saved during an evolution or time-dependent calculation. See Initial Conditions and Initial Conditions for more information about restart files.

You have to provide the names of the results and restart files in Ansys Polydata. The procedure is as follows:

  1. In Ansys Polydata, select the Numerical parameters menu item for the task (for example, in the F.E.M. Task 1 menu).

      Numerical parameters

  2. Select the Start from old result and restart files menu item.

      Start from old result and restart files

  3. When prompted, specify the name of the old results file (e.g., myold.res).

  4. When prompted, specify the name of the restart file (e.g., rst).

  5. Return to the top-level Ansys Polydata menu and save the data file (as described in Writing a Data File).

  6. Follow the instructions in Reading a Data File into Ansys Polyflow to read the data file into Ansys Polyflow and start the calculation, after ensuring that the results file and restart file are in your working directory with the mesh and data files.
