I have a question about adding force to all the atoms in a cubic.
Specific force has to be applied to all the the atoms. And the force is different on different atoms and there is no relation between different forces.
By using ‘addforce’ or ‘setforce’ command, a force can only applied to a group of atoms. However, there is a limit of 32 of the max number of groups, so it is impossible to set each atom to a dependent group.
I want to know what I can do to solve the problem. Thanks.
