Dear all,
I need to obtain the maximum edge length for each one of my cells. My data is a multiblock dataset in .plt format (from Tecplot). I tried with the “Cell size”, “Mesh Quality” and “Extract Edges” that I can use to obtain other metrics like volumes, edge ratios and so on but I cannot obtain the edges lengths (or at least the maximum/minimum) for each individual cell. Is it possible to create a variable with the length of the longest edge for each cell? Thank you in advance!

one way is to write a script for the programmable filter. The example below iterates all elements and calculates volume which assigns to an array:

in your case you will need to have an extra outer loop to go over each block but you can start with applying `Merge Blocks` first and apply the programmable filter on its results. Once satisfied you can edit it for multiple blocks.
