I use the microfluidics level set module to solve a time-dependent two-phase flow problem. I want to export the interface at all times. How to do this?
Essentially I just want to export the coordinates of the phi=0 contour (basically the zero contour of any 2D data, can be anything in any modules). I know I can just export the variable phi, but I will just end up with GBs of data which I cannot even open with notepad directly as the file size is way too large (and I just need to know the contour, not other thing else). I can also right click my contour plot and select export, but then it only export the coordinates of the contour at one time. I want the coordinates at multiple times.
What's the best way (in terms of memory storage and ease of access) to do it? Ideally, I want just want a file which lists the (x,y) coordinates of the contour at selected times.
