Mesh Convergence issue in Higher order model

Thu, 18 Mar 2010 02:39:45 +0000

Hi Everybody,

I am modeling non-linear (5'th order) stress-strain relation with 4'th order PDE for a smart material.
When ever I refine the mesh, my end results have different contours. I refined the mesh number of times but problem persists. Now I don't have computational capability for further refined model. Is it because of high non-linearity?

Does anyone know how to resolve this mesh convergence issue?
Please share your expertise.

Thanks,
Rakesh
