Run the simulation for twice as long (30ms) as described in the documentation (https://github.com/openworm/OpenWorm/blob/master/README.md). Upload the new worm_motion_1.png image generated in the new output folder.
Use the first instruction under "Advanced" to run the simulation for twice as long at 30ms instead of 15ms.
./run.sh -d 30
Upload the new worm_motion_1.png image generated in the new output folder. This should show up in the form of a folder with a different (later) trailing time-stamp. The new image should have a chart header that indicates a run duration of 30 ms instead of the default 15ms.
