I have written my lid-driven code with SIMPLE on MATLAB following the instruction from Ferziger's book. And I want to change it to get a PISO case, however, it occured to me that due to previous work based on the colocated grid, the cant be obtained directly on the colocated grid. So I think that I need to interpolate the nodal value to get that.
The question is : Can be calculated by simple interpolation or something like momentum interpolation? Or PISO requires a different way to implement on the colocated grid, which is not same with the description in Ferziger's book? I will appreciate it if you can provide any suggetion or tutorial. Thank you in advance! |
