I am new to Ansys. Apologies if the questions are repeated. If so, Please link me to similar posts.<\/strong><\/p>\n

<\/p>\n

I am trying to simulate eccentric axial loading on a hollow beam of circular cross section. I have Large Deflection as on. I have numbered and put the questions in bold throughout my post.<\/p>\n

<\/p>\n

The dimensions of my beam are as follows:<\/p>\n

<\/p>\n

Inner radius: 0.3 mm<\/p>\n

<\/p>\n

Outer radius: 0.4 mm<\/p>\n

<\/p>\n

Length: 35 mm<\/p>\n

<\/p>\n

Basically, it is a thin cable. For now, I have kept the material as steel. I intend to use superelastic material properties eventually.<\/p>\n

<\/p>\n

I have meshed the part with the parameters as shown. I just followed an online example (I have no clue as to which Physics Preference and Solver Preference to use, but Mechanical gave me a very non-uniform mesh).<\/p>\n

<\/p>\n

\"Mesh<\/p>\n

<\/p>\n

1) Is there a proper manual\/documentation as to what meshing is to be used for which situation? How do I get a uniform mesh which is axisymmetric?<\/strong><\/p>\n

<\/p>\n

I applied fixed support on one face of the beam. On the other face, I want to apply a force as shown below:<\/p>\n

<\/p>\n

\"Example<\/p>\n

<\/p>\n

However, when I choose Static Structural>Loads>Force and select a point on the face, I select the whole face:<\/p>\n

<\/p>\n

\"Actual<\/p>\n

<\/p>\n

I know that I can choose to insert a remote point and apply a remote force, or choose a point of application using Element Node selection.<\/p>\n

<\/p>\n

2) If I define a remote point, and a remote force on it, does it continue to apply as the beam deforms? As in, does the remote point move along with the beam as it deforms so the force continues to apply at the point?<\/strong><\/p>\n

<\/p>\n

(I believe the above is true, because the beam does deform quite a bit, so my intuition says that obviously the force applies throughout the deformation process)<\/p>\n

<\/p>\n

3) How can I apply my eccentric axial force over a local area on that face of the beam? Say, over a circular area between the inner and outer radii, on the rim.<\/strong><\/p>\n

<\/p>\n

4) If I apply my force and define it either by Vector or Components, does it remain perpendicular to the surface as the beam deforms? Or do I need to use pressure in this case? If the latter is true, then what is the answer for (3)?<\/strong><\/p>\n

<\/p>\n

I know that my beam deforms quite a bit (hence large deflection) and that my load should always remain perpendicular to the surface of the face of the beam, at the same point\/location.<\/p>\n

<\/p>\n

Please let me know if I need to give more details. Thanks<\/p>\n
