How to use checkpointing to restart OpenFAST simulations

Hello,
In OpenFAST main file, I can change the ChkptTime argument to a different value, say: 10 to save checkpoints every 10 seconds.

I tried searching online, and also checked OpenFAST repository online, to find some examples on how to use these .chkp files to no avail.

When I run OpenFAST simulation it starts from time 0 and it doesn’t seems to use the checkpoint files by default.

How do I tell OpenFAST to use a specific checkpoint file to resume the simulations?

Best regards,

Dear @Yoor.Thiziri,

To restart OpenFAST from a checkpoint file, you should type:

<name of OpenFAST executable> -restart <root name of checkpoint file without extension>

For example:

C:\openfast_x64 -restart Test18.1800

which will start from Test.18.1800.chkp.

Best regards,
