you looked at this? https://www.wolfdynamics.com/training/movingbodies/OF2021/dynamicmeshes_2021_OF8.pdf

could you explain what you want to simulate so we could understand you problem? because usuallyyy fluids dont pass through walls, and things like the cylinder also dont because welllll stuff colides

Because I have something like his https://cdn.discordapp.com/attachments/400697259819270145/1448698062703689808/image.png?ex=693c34b5&is=693ae335&hm=0fb9eb92f76350190488eb42d4d2a12d5bf9f6d86fd6435f0083819a64b8709a&

And I want to make the cylinder rotate but I am not entirely sure where to put the AMI interface and how it is supposed to look

ah thank you they seem to have a suiting setup ❤️

their shaft is my cylinder

This will be a bad question and I know. If you have oscillating residuals for given object changing solver and preconditioner do not help. Incorporating underrelaxation will that help? I think this should be a fairly common thing in CFD?

I tried this and all the options on the linked forum post and none worked 😔 but Ty

Contour is U mag, does anybody know why? could it be my mesh?

boundaryField
{
    prismWall
    {
        type            noSlip;
    }

    farField
    {
        type            freestreamVelocity;
        freestreamValue uniform (0.0015 0 0);
        value           uniform (0.0015 0 0);
    }

    frontAndBack
    {
        type            empty;
    }
}

It would help if you show the mesh

checkMesh doesnt spot anything

is the farfield BC given or can you replace it, I would try it with an inlet instead of farField

Uh not really im just winging things

Okay ill try inlet and let yall know how that goes

Computation is very slow tho, my snappy grid performed way better But then again could be the BCs acting up

I assume you applied the corresponding

freestreamPressure

for p?

I haven't used

freestreamVelocity

, but 0.0015 seems like very low velocity? I'm not sure if that plays a role though..

yup

farField
{
    type            freestreamPressure;
    freestreamValue uniform 0;
    value           uniform 0;
}

re 100

or is this a better strat for meshing? https://cdn.discordapp.com/attachments/400697259819270145/1449849126756941956/content.png?ex=694064b8&is=693f1338&hm=6b35550d24e671c69535b96139deac53d21c7200fbfca826689c4eedb854a5e8&

That would be a polyhedra, not sure if that is simply possible like that

wdym simply possible like that?

Your decomposition is not made of all quads, so it won't produce a conformal hex mesh

ooooooOOoo

would you say this is a viable thread i should follow?

this was mentioned^

oh sorry, i dindt see it!

I have a non conformal mesh from fluent transfered to foam When using stitchMesh on the two integral patches the following it gets stuck on, nothing happends no error message anything? Anyone has ever come across this, a simple google search didnt result me any direct threads where people came across this.
