Hello, I made a mesh via Salome and when I want to import it, I get the error "controldict file not found". What do you think is the reason for this? How can I solve this problem?

Hello,

You need to run the command from a directory using the OpenFOAM case structure, i.e. with a system directory containing a controlDict file.

Hello sir, I have a small problem. I will tell you everything. I would really appreciate it if you could help me.

My boundary volume is a cylinder and there is a sphere inside this cylinder. I want this sphere to fall to the ground under the influence of gravity. This is my problem.

Cylinder Radius: 15, Height: 50 , Sphere radius: 2.5

Can you help me write my dynamicMeshDict file

dynamicFvMesh dynamicMotionSolverFvMesh;

motionSolverLibs ( "libfvMotionSolvers.so" );

solver displacementLaplacian;

displacementLaplacianCoeffs
{
diffusivity uniform;
}

solidBodyMotionFvMeshCoeffs
{
cellZone innerCylinderSmall;

solidBodyMotionFunction freeFallMotion;
freeFallMotionCoeffs
{
origin (0 0 0);
velocity (0 0 -9.81); // 9.81 m/s^2 yerçekimi ivmesi kullanarak düşme hızını belirtir
}
}

I solved the controldict error

Where did you get "freeFallMotion"?
AFAIK there is no such thing in solidBodyMotionFunction.

If you want to model a free fall, you should use sixDoFRigidBodyMotion instead. Have a look at the tutorials using it.
You can find it using this command:
