Hello,  
I used to download force field files from [https://www.gromacs.org/Downloads/User\_contributions/Force\_fields](https://www.gromacs.org/Downloads/User_contributions/Force_fields) , but it seems like this page is no longer online.

Is there a new address I can use for that?

Thank you in advance,  
Leandro

Hi,  
we have released a new gromacs page, that is the reason behind user contribution page not be online. We are working to make user contributions accessible again. I will inform you once it is done.  
Best regards

Hi Leandro,

you can find the link to the old user contributions here [User contributions — GROMACS webpage https://www.gromacs.org documentation](https://www.gromacs.org/user_contributions.html)

New users contributions are hosted in the [Third party tools and files - GROMACS forums](https://gromacs.bioexcel.eu/c/third-party-tools-and-files/8)
