Setting up a DOE

Submitted by mschramm on Mon, 10/29/2018 - 20:33

Hello,
I have been making DOEs by utilizing the universe variable type

variable var1 universe 1 2 3 4 5
variable var2 universe 0.1 0.2 0.3 0.4 0.5

# DO THINGS WITH var1 and var2

next var1 var2
clear
jump in.liggghts

Is there a way to use the file variable type to read in all of my DOE values from a txt file?

I have tried
variable var1 file vat1_vals.txt
variable var2 file vat2_vals.txt

but when I call

mpirun -n 4 liggghts -in in.liggghts -partition 4x1

All partitions only use the first value in each txt document.

Any ideas are welcome.

Thank you!

Not sure what you want to achieve but you could use an include:

include "vat1_vals.txt"

and in there have
variable var1 universe 1 2 3 4 5

Since you might have a huge list and dont want to do it manually you can start the file with
variable var 1 universe &
and then add an & to each line (except the last one) which you should be able to do rather quickly.
