| Hi Zhiheng,
Good to see you back. We are certainly willing to help you work towards a solution for your problem.
I took a look at the attached PDF file but couldn't make much sense of it. I think we should start by solving one equations with all the other variables fixed and then build up from there. Can you write down a simple single equation to start and then we can add to it as we improve our understanding of the solution.
Cheers

I come back again! I've used another commercial FEA software package for this problem but have been struggling. In particular, the convergence problem and other associated problems. I think I will try to solve my problem using FiPy again since I know you provide much better technical support. I have now simplified the problem a little bit and please find problem description in the attached PDF file. I only have very limited knowledge in FiPy and would be grateful if you could suggest how I should start and if possible provide a template to solve this problem.
Thanks and regards,
Zhiheng

I was wondering if you know of Samjid Mannan and David Whalley? I have collaborated with both of these guys on solder projects in the past where we used the Surface Evolver software to model solder shape. Is your project related to solder?

Thanks very much for your positive reply! Attached please find the article in pdf format. I would be grateful if you could shed some light on how to formulate the equations (11 and 14) in FiPy!
Regards,
Zhiheng Huang

NIST doesn't seem to have access to the electronic version of the Journal you cited. Could you send me an electronic copy of the article?
I would be surprised if the equations in the paper are not solvable in FiPy. However, a little care may be required in stating the equations in a form that FiPy can handle.

I had a quick look of FiPy on your website and I am very interested in this package. However, I am wondering if FiPy is capable of solving the coupled phase field equations (i.e. equations 11 and 14) in the following paper:- J.Y. Huh et al, Phase Field Simulation of Intermetallic Compound Growth during Soldering Reactions, Journal of Electronic Materials, Vol. 33, No. 10, 2004, pp. 1161-1170.
Thanks and regards, Zhiheng Huang Loughborough University UK
