I have a certain flow simulation model with x number of fluid cells and y number of solid cells. Is it possible to only look at data from the fluid cells that are z distance away from the solid cells?

Hi Siavash, thanks for the reply! I think I have figured out a roundabout method to get what I am looking for. Because I can export both fluid cells and solid/partial cells to excel I can compare the coordinate geometry for each fluid cell to the entire partial cell coordinate data set and calculate the minimum distance for each fluid cell to the partial cell boundary using the basic sum of squares distance formula. I can then sort this data by only including coordinate values that give me a distance greater than the z value that I am interested in. The only problem with this method is the data sets are very large (~150000 fluid cells) and excel struggles when trying to compare this much data. I can get the first few thousand cell distances fairly easily, but as this simulation is an iterative process and I may have to go through a number of different results I might have to import the data into another program to do the number crunching. Thanks again!

You went one step ahead of my next response. Yep that's a great strategy. But as a workaround for excel struggling, I would suggest an approximation method: one flow sim GUI, show the mesh and roughly found where the fluid cells are, then by doing through some easy sketch and CAD tricks (which I am sure you know) you can find the approximated target region.

Hi Sam,

I guess there is no direct way to look at results at fluid/solid cells. However, you can narrow down your post processing (eg. a cut plot) to look at a specific region which is in fluid cells with a distance from wall boundary.
