hey,

actually, I just figured I do have access to fluent. so, sorry for the mistake on my side, I thought fluent is not available on the machines I use.

regarding the mesh, my setting was to...

hmm, never got that error. Maybe you need to define something regarding the boundary or the inside of the domain. did you choose them as rigid body?

for the rest, I fear I cannot really say,...

Hi!

So, here's the UDF I used to make a moving wall boundary condition. I used the DEFINE_CG_MOTION udf. With it I moved the horn up and down in our domain, so I'd say you can easily change it to...

Hi!

Firstly, I'd ask, just to know if I got it correctly, is this like an injector with a needle in it? Or is it something else?

could you describe at first the geometry(axisymmetric, 3d, ...)-there was a suggestion here that define_cg_motion might not be an appropriate udf for such simulations. for me it was, but maybe for...

Hi!

Well at this point there is not much I could suggest. I have to admit, my experience in writing UDFs is not very vast. But from kernel32.lib trouble I would assume there is something wrong...

Hi!

Well, .c is the file type in which UDFs have to be saved. For the .h header file I assume that it is asking you for the #include "udf.h" command. and for dynamic meshes you have to add...

Hi Vidit!

I haven't yet come across that someone would compile an udf for Fluent from Visual Studio command prompt. what I always do when I use UDFs which need to be compiled is that I run Fluent...

do you interpret or compile? As far as I know, you have to compile UDFs when you work with dynamic meshes. I have never tried to interpret udfs for dynamic meshes, so I don't know if Fluent even...

hm a bit strange, I would expect it to give no errors this way.

you can see which zone is which if you look at the ID numbers under boundary or cell zone condition dialog box.

i suppose then the boundary you are trying to move is a wall (bottom of the cilinder). I used the given udf for a similar purpose, for moving a whole cilinder in a pool of liquid/another cilinder....
