How do I glue bodies at common faces in Ansys workbench ? (I cant use form parts option)

Hi, I have four bodies in contact with common faces. I can't use "form a new part " feature for four parts. I didn't see any option to glue required solids. I am simulating a fracture problem. For...

How can one merge nodes on two co planar faces in Ansys WB ?

Hi, I am simulating a fracture problem. For that, I split a body into two bodies with slice by plane. That gives two faces at the same location (at intersection of bodies). Again, I split faces on...

How can I create crack surfaces in an already existing 3D model and how can I mesh it using singular elements in ANSYS classic or work bench?

Hi, I used CTMOPT macro in Ansys classic to create semi elliptical crack with mesh in already existing model. But the macro is not working with different a/c ratio. In Ansys workbench tools are...

How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...
