Re: [ESPResSo-users] reading force on particle

[Kai Szuttor]

Can you please show your script or a MWE?

Setting a force on a particle does actually not work since it will be overwritten in the integration loop. That might be the case here. If you want to have a static force, you can use external forces instead.

Best,

Dear all,

I'm trying to do a simulation where I have a polymer chain attached at one end {part 1 fix 1 1 1} and I apply force to the other end {part 100 f [expr 100*sin (simstep/360*pi)] 0 0}, and I try to measure how much of the force is transferred {part 1 print f}, but I don't see those numbers correlated :-)

Please, anybody has an idea what could be going wrong?

Best regards,

Dusan
