Hi all,
I've got 60 single images/states of one geometry. Now I'd like to create the average for each point of this geometry over 60 states.

At the end I wanna get 1 image with the average for each point. Like that I get an overview for examples over the cool parts of my geometry. How can I create that?

I hope you understand what I mean. Sorry in advance. My english is not that good!

Best regards
wlotzi

Wlotzi,

With a transient dataset, where the grid is not changing from timestep to timestep (only the variable value), then there is a built in Calculator function called "TempMean()". This will calculate the temporal mean. It takes each point on the selected part, and computes the average over the timesteps specified. You end up with a new variable, which is a fixed value at each point. You can then color the part with this new TempMean variable.

Let us know if this works for you or not. Sometimes the desired value/operation is not quite what you desire, and we'd be glad to help.

Hi Kevin,
thanks for you answer. Since I work with AMR I think your solution is not the desired one. Correct me if I'm wrong.

Is there a possibility like 'creating' a new grid which doesnt change over time for my results of the AMR simulation in ensight? You got my point what I wanna get at the end. Maybe there is another option.

Wlotzi,

yes, with a grid that changes at each timestep, you cannot physically do any type of temporal average, as you don't have a fixed grid.
However, to get around this, I have in the past, created a sample grid (I took a grid from one timestep, or created my own), and wrote out this single grid to EnSight Case Format. You can read in this single/fixed grid as a second case, and use the CaseMap function to interpolate the results onto. You can then perform the TempMean() operation on this CaseMapped variable which exists on this "fixed" grid. Let us know you need more assistance (I think I have an old video which discusses this if you need more assistance).
