标题: starting structure for MD run
Hi everyone,
I am just starting to learn Molecular Dynamics. My task is to run an MD job of a polymer chain to simulate the self-healing property. I would like to know if the starting polymer for the structure construction needs to be optimised first?
Thank you for your answer

Well, I strongly recommend you to use this tool:

The polymer you establish through this tool is reasonable, so there is no need to optimize the polymer again.

If there is no close contact between any atoms in your initial structure, then optimization (minimization) is not absolutely needed before MD.
