Questions about Meshing in Explicit Dynamics
I have some questions about importing meshed bodies into Explciit Dynamics and about meshing in general.
If a .nas file with a predefined mesh (containing either prism, tetrahedral, hexahedral, or combination of them) is imported into an Explicit Dynamics simulation, does ANSYS subdivide prism elements into tetrahedral elements?
When a mesh containing tetrahedral and prism elements is imported, the mesh is shown to contain Tet4 and Wed6 elements (I'm assuming tet refers to tetrahedral and wed is for wedge elements (ANSYS's term for prism elements) - is this correct?). Or are prism elements broken down into tet elements by the solver before the simulation starts?
Some other questions of interest are:
Can ANSYS take in tet-hex mixed elements? How about pyramid elements?
Can tet elements be directly connected to hex elements? Or is this an issue since tet elements have a triangular face, and hex elements have quadrilateral faces?
Does ANSYS allow for connections between half quadrilaterals (two neighboring hex elements only sharing half of a face)?
Can ANSYS accept connections between a pair of prism elements and a hex element by sharing a quadrilateral from a hex and two triangles from prisms?
