How to implement source term?

Amit Gupta

Hi everyone,

I am a student of Metallurgical & Materials Engineering, Indian Institute of Technology Kanpur, India.

Can anybody tell me that how to implement the source term like d/dx(k(d(phi)/dx)) where phi is other variable than c1,c3.. provided by phoenics.

Is that i have to give whole term as a source in each cell by giving patch type cell....or i have to discritize it and give it as flux on east and west face (patch type east or west)

If i have to discritize this source term then its unit will be changed. One more thing i am working on a trasient problem.

Please help me!! Thanks in advance
