About storing 'solve' data and changing data
How does 'solve' store old values? What is the difference between A and B? It seems that Method 'A' does not work.
Method A: --- changing the value of 'C' here-----
+ fvm::div(phi, C)
- fvm::laplacian(kappaEff, C)
Method B:--- changing the value of 'C' here-----
My best regards,
All GeometricFields have a member oldTime() with a copy of the data of the previous time instance.
Thanks. If I want to change 'C' by assignment after completing 'solve', then whether the GeometricFields of 'C' will be changed corresponding to the assignment.
What exactly are you trying to achieve? Why do you want to change C, and how?
