Hi @mishal49,
can you try if the latest develop branch of the adapter works? This PR may have helped: Displacement reading: Allow mesh motion solvers without a pointDisplacement field by solids4foam · Pull Request #241 · precice/openfoam-adapter · GitHub
(see also I was asked to try a Pull Request. How can I do that?, although this PR is already merged and you can just git pull and git checkout develop, then ./Allclean and ./Allwmake)
