Hi,

 I am trying to mesh a solid in CAE using HEX elements. For some reason, I am getting an error message saying that the element topology is not right for the geometry.

 I eventually want to do crack analysis and so hex or wedge elements are essential for my model. Could anyone please help me and let me know if there is a way to go around the problem and get a hex mesh on the solid. I am attaching the .jpeg file of the geometry of the solid I want to HEX mesh.

Thanks a lot in advance

Very Much thanks to Mike for introducing Web 2.0 to me, I become more and more interested to Web 2.0, Imechanica in fact is part of this.

Hi All ,

I found  simple VUMAT from Abaqus manual.It is based on

Von Mises plasticity and gives stress components, vonmises stress

and plastic equivalent strain.

I want to include the adaibatic temperature that rises/falls along the deformation in adiabatic

analysis.From a general book, i found that temperature-rise during deformation comprising

plastic strain1 to plastic strain 2 is given by:

Integral of stress between the strain limits,multiplied by a constant.
