Hi,
I am trying to compute contact force with paticles through the compute/gran/local command. I have use a loop command and when it loop, it shows an error as "ERROR: Need to define compute pair/gran/local or wall/gran/local before first run (compute_pair_gran_local.cpp:91)". Does anyone know how to modified it? I have attached my input file. Thanks.

compute/uncompute command
You missed something in compute/uncompute command. Comment the line #50 and #52 and your script does not produce an error.

Hi AGI,
Hi AGI,
I do not know what has missing of the compute/uncompute command. You mean these two lines "compute l all pair/gran/local pos force contactArea", "uncompute l". Could you point out what has missing? Thanks very much.

uncompute
It seems, you "uncompute" before the values are calculated. That is why you get this error. If you remove last 3 lines of your code, it does not show an error any more.

Compute pair/gran/local (id cpg2)
Hello
Getting following error while running the following command in the loop in LIGGGHTS.
Here $a is variable
compute cpg$a all pair/gran/local pos vel force force_normal force_tangential del
ERROR: Compute pair/gran/local (id cpg2): Need to define this compute before first run (../compute_pair_gran_local.cpp:127)
Any comments on the above state error.
Thank You
