** Normal procedure [#le4c697d]

- Obtain a sample UDF file.

- Start "Gourmet" and open the sample UDF file. Modify it for your own purpose and save it as "input.udf".

- Run KAPSEL as follows.

    > ./kapsel/kapsel -Iinput.udf -Ooutput.udf -Ddefine.udf -Rrestart.udf

- Start "Gourmet" and open "output.udf". Load "plot.py" etc to visualize your simulation data. ([[See STEP4>InstallB]])


** Re-start run  [#u7810c9a]

- One can re-start simulations from the end of the previous run.

- Start "Gourmet", and open "restart.udf"

- Set "resume.Calculation" = "CONTINUE"

- Increase "output.Num_step", and save it as "input2.udf"

- Run KAPSEL as follows.

    > ./kapsel/kapsel -Iinput2.udf -Ooutput2.udf -Ddefine.udf -Rrestart2.udf
