Hi Hanbo,
You are getting this error in parallel because this test case is using the option
<I PROPERTY="GlobalSysSoln" VALUE="DirectMultiLevelStaticCond"/>
and the direct solver only works in serial. You can run it in parallel by changing this option to IterativeStaticCond or XxtMultiLevelStaticCond.
To visualize the movement, you have to use the mapping module during postprocessing, i.e.
FieldConvert -m mapping CylFlow_Mov_mapping.xml CylFlow_Mov_mapping.fld cyl.vtu
This way the vtu file will have additional fields xCoord and yCoord containing the x and y deformed coordinates. If you are using paraview, you can then create a Calculator with the expression
"xCoord*iHat + yCoord*jHat + coordsZ*kHat"
and activate the "Coordinate results" option to visualize the deformed geometry.
Cheers,
Douglas
