moving meshes: non-uniform moving body
 
Hi!

I am attempting to solve the flow around a solid body which moves by the relation v(x,t)=f(x)*f(t).

My question is:

Using pimpleDyMFoam with the dynamicMotionSolver in the pointMotionUx file is it possible to use a timeVaryingMappedFixedValue BC (I'm assuming this is an unsteady non-uniform BC)?

Is there a simpler way? All the tutorials seem to have motion that is uniform... I'm not afraid of hard coding something in but i'm a converting fortran programmer so please be kind :)

I think you can use TimeVaryingUniformFixedValue BC.

Hello foamers,

can every one tell me exactly what is pointMotionUx and cellMotionUx files in the moving cone?
I am trying to solve the flow around a solid body which moves by the function dependent temporal and spatial variables, how can define a function to move the solid body? any suggestion...

Thanks
