Rida Bensailaa, Attached, you will find the partition I quickly generated using the pyautocad library. I have included the resulting file and a .stp file for your reference. I'm sure, these will be of assistance. Additionally, I have included some ABAQUS screenshots for your understanding. Good luck !
To create a sphere partition inside a cylinder in ABAQUS you can create the Cylinder Geometry: You can use the "Part" module to create the cylinder geometry. Then "Create Cylinder" tool and specify its dimensions. After that you can create the Sphere Geometry using the "Create Sphere" tool and specify its radius and position.
Then you can create a Partition, so you will need to subtract the sphere from the cylinder.
So, I can suggest that you use the "Part" module's "Partition" feature to split the cylinder using the sphere. Select the cylinder as the target and the sphere as the tool to create the partition. This will effectively cut out the sphere from the cylinder. After partitioning, you will need to generate a mesh for the geometry. Use the "Mesh" module to create a mesh for both the cylinder and the sphere, making sure to specify element types, mesh size, and other meshing parameters as needed. Define material properties for both the cylinder and the sphere, depending on the material you want to simulate. And do not forget to set up boundary conditions and apply loads to your model according to your simulation requirements.
