Heya, No, I did not impleme

Heya,

No, I did not implement radial basis functions and indeed I know very little about the subject. Basically, if you want to move the mesh in OpenFOAM, all you need to do is to calculate the...

Try running it the with mesh C

Try running it the with mesh Co number of 0.5 and see if it gets any better.

The Thesis is being translated (I know, there was nothing I could do about the choice of language at the time). It...

Yup, I've already done that: m

Yup, I've already done that: make a subset, create a motion solver on it. Once the motion is solved for, use the functionality of the subset to map onto the complete mesh for motion and you're done....

Heya, Nice to hear you got

Heya,

Nice to hear you got it working.

1) You need tuning. First, choose a better diffusion algorithm to limit mesh deformation next to the moving boundary. Second, carefully tune solver...
