Wing Motion - Dynamic Mesh using pimpleFoam


I am trying to test out a flapping wing case. I started out with the tutorial case in pimpleFoam/wingMotion. Although I did follow all the steps, the final mesh does not move - the flapping wing motion does not occur. The other sub cases like wingMotion_snappyHexMesh and wingMotion2D_simpleFoam work fine, but the last step alone is troublesome. Can anyone help me with the same?

In Allrun file you can see how the tutorial is copying files between folders after running some commands. Check if you missed anything.

Hey, Thank you for replying! I have ensured and cross-checked that all commands described in Allrun file are executed except the decomposePar. As I have issues with running on parallel I have stuck to running the solver the usual way. Could that have affected the solution? Any help is greatly appreciated. Thanks!

I ran the same simulation using Allrun script. It is showing results with moving mesh.
Can you explain the procedure you followed to run the simulation?

I ran the same sequence of steps with pimpleDyMFoam solver and it works perfectly fine now. 

Thank you for your time.

I followed the same steps sequence with the pimpleDyMFoam solver. Can you explain the process you followed to run the simulation? Minecraft Classic
