Running ASTE in serial

Using preCICE
1

Hi,

I am having some trouble running ASTE in serial. I want to do this to identify issues with the partitioning (see Sub-domain splitting lines visible with ASTE). I tried the following setup given two valid meshes mesh_1.vtu and mesh_2.vtu:

precice-aste-evaluate -m meshes/mesh_1.vtu -f "franke3d" -d "InputData" -o input_mesh.vtu --log DEBUG
precice-aste-run -p A --mesh input_mesh --data "InputData" 
precice-aste-run -p B --mesh meshes/mesh_2.vtu --data "InterpolatedData" --output mapped
precice-aste-evaluate -m mapped.vtu -f "franke3d" -d "Error" --diffdata "InputData" --diff --stats --log DEBUG

The precice-config.xml looks like this:

<?xml version="1.0" encoding="UTF-8" ?>
<precice-configuration experimental="true">
  <log>
    <sink
      filter="%Severity% > debug and %Rank% = 0"
      format="---[precice] %ColorizedSeverity% %Message%"
      enabled="true" />
  </log>

  <profiling flush-every="50" directory="." mode="all" synchronize="true" />

  <data:scalar name="Data" />

  <mesh name="A-Mesh" dimensions="3">
    <use-data name="Data" />
  </mesh>

  <mesh name="B-Mesh" dimensions="3">
    <use-data name="Data" />
  </mesh>

  <participant name="A">
    <provide-mesh name="A-Mesh" />
    <write-data name="Data" mesh="A-Mesh" />
  </participant>

  <participant name="B">
    <receive-mesh name="A-Mesh" from="A" />
    <provide-mesh name="B-Mesh" />
    <read-data name="Data" mesh="B-Mesh" />
    <mapping:nearest-neighbor constraint="consistent" direction="read" from="A-Mesh" to="B-Mesh" />
  </participant>

  <m2n:sockets acceptor="A" connector="B" exchange-directory="." />

  <coupling-scheme:serial-explicit>
    <participants first="A" second="B" />
    <max-time value="1.0" />
    <time-window-size value="1" />
    <exchange data="Data" mesh="A-Mesh" from="A" to="B" />
  </coupling-scheme:serial-explicit>
</precice-configuration>

When trying to run this setup, the generated mapped.vtu is not formed correctly and cannot be used by the last call to precice-aste-evaluate. Is it possible to run ASTE in a serial manner?
