Hello All,

We know that in OpenFOAM/system/controlDict, we can set the writeInterval, eg., 0.1 and my end time is 500. I can also set purgeWrite to be 6, then it will only store the latest 6 writeInterval steps, eg. 400.1, 400.2, 400.3, 400.4, 400.5, 400.6 if my simulation has run for 400.6667.

I am wondering whether the restart command in liggghts has the similar functionality.

Thanks and best regards,
Min

No there is no such functionality directly. Writing two restart files alternating might be of interest for you and that can be achieved with the restart function.

Hello,

Thanks for your reply!

But on the OpenFOAM website, https://openfoam.org/download/history/, it has the OF5.0 version already released.

I have been trying to install OpenFOAM&LIGGGHTS&CFDEMcoupling on a cluster and its OS is CentOS Linux release 7.4.1708 (Core).

I found that OF4.1 and OF5.0 has already been installed on this cluster. So I am wondering whether I could be based on their OF5.0 or I need to install OF5.x by myself since the latest CFDEMcoupling version is only compatible with OF5.x not OF5.0.

Thanks and best regards,
Min
