Transient thermal analysis

Hi,

I have developed a 2D transient thermal analysis FE code which doesn't
seem to be correct. I am sure there is a conceptual problem in the
formulation itself which I have not been able to understand and could
not find concrete information in books.

I am putting up the question in a very simplified form so as to address the correctness of the formulation.

Let's say we have a square of unit length with 4 nodes at each corner
(Q4 element). Initial temperatures are specified as 100 for all nodes

Hi dears

Would you help me about Abaqus learning?

As I search in diffrent web pages and data base

there is not enough refrences about abaqus tutorials

so How can I learn it as a begining user?

thanks for your help

good luck

Hi Dear iMechanica followers

I came accross a problem when defining displacament boundry conditions. I have been modeling cutting simulation in micron size. so I need to define tool cutter path in a circular shape. I mean cutter should follow the circular or parabolic path not smooth line. To do this I am trying to define analytical distribution in boundary conditions but it doesnt work. I attached the shematic picture of my job of what I want to do. please look out the attached pdf file and send me your suggestions.

Thanks in advance

Nanotubes

Hi folks! I deal with buckling nanostructures, contact problem of nanostructures. And i have a problem with geometry construction of nanotube with arbitrary (n, m) chirality. Can any one write the algorithm for building nanotube geometry in 3d space(xyz-Cartesian coordinate system). Many thanks!
