In transient case ,I want average scalar values at wall from all timestep. So I could export data to FEA Analysis.

Thanks in advance

This can have two answers:

1. If you want the average over the whole surface as each timestep, then create an area average report of the scalar then a monitor from that report (change storage from iteration to timestep), then export the monitor at the end of the solve.

2. If you want the average value at each location (cell face or presentation grid) on the wall over the whole run then the only way I can think of is to export a table (create the table from the wall locations or a pres. grid) of values at each time step then write a little program to read each of these and average each location.

Thanks, I think second option is better
