Dear Sir: I am trying to use FlexPDE as a solver for each case specified by other software. I ask FlexPDE output the calculated result to an output file, so that I can open the file and analyze the data from the application software. I currently use Plots section to do the job such as the following 1D script with a variable phi Plots history(B, EVAL(phi, d)) export format "#1#b#2" file="NLC_twist.txt" history(B,integral(cos(dk*x/d)*dx(phi),"linecell")) export format "#1#b#2" file="NLC_tm.txt" Unfortunately I have to repeat the calculation twice by using Stages=2 in order to use Stage-history combination. Is there a easier way to output the integral of the solution or the value of the solution at a specified location? Thanks! Jung Y. Huang | ||

You will still need to use VAL or EVAL to compute the value at a point, but you can use a SUMMARY plot with REPORT statements to write the values without resorting to a fake History (see SUMMARY in the Help Index). You can EXPORT a SUMMARY plot, but cannot use a FORMAT. You simply get what the SUMMARY writes. But the available controls for REPORTS should let you construct what you need. | ||

Thanks! Dr. Nelson, It works! Based on your suggestion, the final script to do the file output from FlexPDE is: Summary Export file="NLC_Output.txt" REPORT(B) as 'B' Report (EVAL(phi, d)) as 'Phi(d)' Report (integral(cos(dk*x/d)*dx(phi),"linecell")) as 'Ret' I can now execute FlexPDE in my Fortran program and perform model parameters extraction.
