Support in FEM

Submitted by Papp on
Good morning,

I'm dealing with an structrual static analysis of a shaft in Ansys WB. The shaft is supported by bearings and loaded by a torque. I tried to replace bearings with "Cylindrical support". (Radial - fixed, Axial - fixed and Tangential - Free) but I am not realy sure that this support work. Is it good manner how to replace this kind of support in 3D analysis because the Ansys shows the warning that about rigid body motion etc..

Thanks in advance.

Good morning,

I'm dealing with the model of a tank and I'm using the finite element software Abaqus. Unfortunately, I'm totally new to this program and so I have the following very trivial problem: I've to model a tank with two different thicknesses, 30mm in the bottom part and 15 mm in the top part. How can I do that?

I've to create the 2 different parts separately and then put them together in the assembly? In this case, how can I manage the interaction between the two parts?

Or there is another method (for example using the discrete field tool)? Which is the most efficient method?

Thanks in advance.
