Infinite neutron plane source in the vicinity of slab

[aser]

hello
I solve neutron diff eq for plane source in the vicinity of slab of water but if i substitute source term with 1 the flux in some places is greater than one! how it possible?! i am sure about my calculation so someone say me how it possible?

If one has a flux gradient, then the average value will be between the high and low values. For example, on a line between 0 and 1, the average value is 0.5. If one is an average value, then the low could be 0.9, while the maximum would be 1.1.

Hello,

It is possible for the flux to be greater than one in some places if the source term is substituted with a value of 1. This could be due to a few reasons:

1. The boundary conditions of the problem may not be properly defined, leading to incorrect results.

2. The mathematical model used to solve the problem may not accurately represent the physical system, leading to unexpected results.

3. There may be errors in the calculations or assumptions made during the solution process.

I would suggest double-checking your calculations and assumptions, and also considering the limitations of the mathematical model you are using. It may also be helpful to consult with other experts in the field for their insights and advice.

I hope this helps. Good luck with your problem-solving!
