now I can use the command " track record=on echo=on ... " record the data of x,y,z,and time of each particle tracked to scalar field (RSF file) in the type of Part_number of particle_x or y or z or time, such as part_1_x. then I have to use the function "advanced input/output" under the "file" menu in GUI of Tascflow to write the data I need (from part_1_x, ... to part_100_time) into 400 files respectivlly :--( then I use ftp transfer these files to my computer to calculate the blood damage.

maybe you have found that all these work are repeatly. I mean in the procedure of output the data I need, what I do is: step1, click "advanced input/output" under the "file" menu in GUI; step2: in the window of advanced input/ouput, select RSF in type, write in operation, give a file name in file, such as part1x.dat, up to the data I write, region don't need to give or change, write the scalar name in Data fields, such as part_1_x, then click OK button, then one file named part1x.dat incluing the data of part_1_x was stored. after this, I go back to step1 to output part_1_y into part1y.dat. what I change are only the scalar data name and file name.

so I think there maybe some method such as macro or sth like .bat file in dos or a little program in unix can operate the RSF data directly and do the repeatly job for me, but I am not familiar with the command line type of Tascflow and Unix command, so could you give me some idea about these.

thanks in advance!

If you go to the Macro Manager under the Tools menu in the GUI. You can then type in a set of repeated commands you want to use. I used the macro below to read in transient data from the rso and then write the data to a rsf file for each iteration of my solution. See chapter 8 in the user manual for the specifics on using macros

$1 = is the argument statement when executing the macro aa = the number of iterations in my solution ii = a count that is performed to end the while loop once all of the iterations have been read and written.

-- Macro write_transient_to_rsf define parameter activeregion=center_line define parameter aa=$1 define parameter ii=1

calc aa=$aa+1

while ($ii < $aa)

read rso iteration=$ii

write rsf rsf_fields="j t_solid" to /homedirectory/filename$ii.dat

echo Run $ii of $aa is complete

calc ii=$ii+1
