Hi everyone,

I'm trying to digitise the total/stagnation pressure distributions of a boundary layer ingesting engine. I have a lot of experimental and computational data from past work but I'm struggling to convert it into a vtk format. My current approach is creating a csv file with engauge by manually drawing lines along each pressure contour line but the limitation is that it only creates separate lines when the contours are uniformly distributed or almost flat and the majority of my dataset is highly distorted.

I'm using a simple MATLAB code which converts a csv file into a vtk file however, it only works when it has the same x-coordinate for every line. Since most of the pressure distributions at high angles of attack are non-uniform, engauge is not able to capture these contours separately and I can't create a suitable csv file for MATLAB to convert.

I looked everywhere for a similar software to engauge but every other approach gives me separate x values for each line. Is there any other way I could digitize this data? I though of changing the MATLAB script to accept separate x values but I'm not sure how to go about it.

Hopefully it makes sense. I uploaded an example of what I'm digitizing.

Thank you in advance.
