Using parameter files, file naming and extraction of results

Hi,
I would like to achiev the following:
- a model has to be solved with ONE varying parameter, e.g. flowrate at the inlet has to take the values "1,2,4,6,7,8"
- after solving for a parameter, several variables, e.g. "'U_mmglf" or "p" have to be integrated over a selected domain using postint (for example "I3=postint(fem,'U_mmglf'....")
- I3 should be written to a textfile with "save filename I3 -ascii"
My problem now is, how to save the integration result for each parameter in a separate file which is named according to the parameter. I thinks this is an easy one, but I am blind to find the right syntax.
Is there any command to write the results for I3=postint(...) into one file, e.g. by appending entries during each step through the parameters " 1,2,4,6,7,8" in the textfile generated?
-------------------------------
Another question is how to read selected parameter pairs from a parameter file?
For example if the entries are {1 5 2 7 3 11} but I would like to select only the pair {2 7} to solve for. The idea is to set up loops according to "for i = 1:nSteps" and somehow use "i" to point to a position in a parameter file and read out the corresponding value pair as input for solving. Is there any solution to this?
Thanks for help!

Hi
have you checked the "solve - solver manager - sequence" and/ or "Solve - Parametric Sweep* tab ? With the latter you can generate different files of the solutions

Good luck

Hi Ivar,
thanks for your response.
I used the parameteric solving and storing of solutions in separate files in the past. The problem is, that I still had to go into these solution files and do the integration of the subdomains manually to retrieve the values.
