[gmx-users] Analysis pull code simulation data to obtain Strain Stress curve

[Md. Imrul Reza Shishir]

Dear Alex

My initial target to obtain nanomechanical properties of cellulose
nanofibril. I have an 18 chain Cellulose Iβ structure of 20 residues. I
want to obtain the young modulus of the fibril my molecular dynamics.

But I am confused how I can approach to obtain this target.

Thanks for the response. And wish some guidance.

Best Regards
Md Imrul Reza Shishir
