Saving results & restarting in a parallel run

[hanbinglele]

Hi, All

I partitioned an extruded mesh into 4 partitions and then tried to run surface relaxation on this partitioned mesh in parallel way.

Code: Select all

mpirun -np 4 -bind-to-none ElmerSolver_mpi

In the simulation section(SurfRelaxation.sif), I saved the results as the restart file for later inverse methods.

Code: Select all

[color=#800040]Simulation
  Coordinate System = Cartesian 3D
  Simulation Type = "Transient"
  Timestepping Method = "BDF"
  BDF Order = 1
  TimeStep intervals = 20! how many timesteps between writing outputs
  TimeStep Sizes = 0.1 !timestep size in years.

  Steady State Min Iterations = 1
  Steady State Max Iterations = 1

  Output Intervals(1) = 1!how many timesteps between writing outputs

  !Contains data for restarting
  Output File = $name".result"
  !Contains ElmerPost data
  Post File = $name".ep"

  Max Output Level = 9
  Initialize Dirichlet Conditions = Logical False
End[/color]

Normally the output should be $name.result.0, $name.result.1, $name.result.2, $name.result.3. But there is just one result file generated ($name.result). Then while I used the restart file in Inverse Methods(inversion.sif), error comes to me while running the second timestep.

Then I have no idea what is going wrong. I think it should be the saving process during the surface relaxation. But i don't know how to fix it.
