As I already mentioned, the moving mesh stuff is only present in interFoam 1.3.

Here is a nice testcase of a plunging cylinder submerged in water.

Hi Srinath,

Up to know, I am not able to explain the difference between OF-1.3 and OF-1.4 for moving wall cases. But, after some more tests, I found the following:

1) Using moving cylinder...

yes, I use the last versions of those time schemes. I did simulations with Euler implicit, Backward and Crank Nicholson (CN=1.0), all with similar differences between OF-1.3 and OF-1.4.

yes. The new OF-1.4 also works with the 'old' OF-1.3 definition of solver settings. The only thing that is different is the way the mesh moves. OF-1.3 uses the tetDecomposition stuff, whereas OF-1.4...

Dear Hugo, That would be n

Dear Hugo,

That would be nice, but how do you know that your comsol solution is correct? The problem is that when I compare the mean drag coefficient, obtained using both OF-1.3 and OF-1.4,...

I can't use this moving mesh in Fluent (the only other code that we have). Right now, I try to do a comparison with literature (drag coefficients) on larger domains and denser meshes. We'll see what...

Hi everybody,

As I showed on the workshop 2 weeks ago, the 'new' finite volume mesh motion solver is a lot faster than the other decomposition motion solvers. (At least, for my cases)....
