I've been studying ANSYS v11 from a book I bought online. I remember doing the same during my graduation. Now that I am studying in-depth I'd like to know why meshing is required (in more technical terms). Also, I am solving 2D truss related problems where I realise meshing is not done. However, when I checked online 2D truss tutorials suggest implementation of meshing. So what's the right answer? Is it necessary? Ps. Additional question: I assumed that meshing is something which is attributed only to 3D members. Is this correct? Please help.
