 I want to study dynamic response of plates using element free galerkin method. But i have difficulty imposing essential boundary conditions. I have tried Chen's full transformation method. Can someone tell me how to impose essential boundary condition to solve eigen value problems?

FEMLAB-COMSOL Multiphysics

Submitted by Catherine on

Hi,

I am a PhD student and I have just started to work on FEMLAB and was just wondering if someone could help me with FEMLAB. I am using at the moment the PDE modes-Weak forms to solve flow over topography using the lubrication equation. I have implemented the lubrication equations into the subsomain settings and set the boundary conditions  but i do get wrong results. Could you please advice where i might have done wrong.
Any suggestions will be really appreciated.
Many thanks
Catherine

 

Some loud (and crazy) thinking on automobiles...

At iMechanica, almost none talks about topics from structural dynamics and design, theory of machines, automotive mechanics, space mechanics, etc.

Let me help correct this situation by raising two questions below. Well-thought answers from any individual are welcome.

First, some background for the questions.

H-M coupled problem

Hello, I'm working in my doctoral thesis. I work in drying cracks in soils. At the moment I'm starting to implement my code but I want to start with simplest case.

My problem is high nonlinear and for this reason I need to solve for example flow in unsaturated porous media. Are there any code in matlab to solve nonlinear problems in 1D ? for flow in porouos media or for heat transmition it could be useful for me.

Thank you very much.

HI ALL


Actually I  am a Student of 2 year M. Tech. studying in S. V. National  Institute of Technology, Surat My name is Zoeb K Lakdawala. My topic for disseration is 'Implemenation of Fracture Mechanics on Pressure  Vessels". In my disseration I want to develop a code on fracture mechanics and compare it with standard Packages like ANSYS & ABAQUS.
