hi:
for fsi in xml file, i should use data “force” or use data ‘displacement’ or use “force” and 'displacement" at the same time as follow, and why?

I am not sure about any references to read about this, but in our examples, we typically accelerate (post-process) both. This should be the safe default to start from. See, for example:

github.com

precice/tutorials/blob/master/perpendicular-flap/precice-config.xml

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

  <solver-interface dimensions="2">
    <data:vector name="Force" />
    <data:vector name="Displacement" />

    <mesh name="Fluid-Mesh">
      <use-data name="Force" />
      <use-data name="Displacement" />
    </mesh>

    <mesh name="Solid-Mesh">
      <use-data name="Displacement" />
