Hi
In OpenFoam is it possible to know the old time step value of any variable. I know it is pobbile to write the value in the disk in each time-step. My question is, how to handle with those?

You can store old time field using:

fieldName.storeOldTime();

and recover it using:

fieldName.oldTime();

Look here for further information:

Thanks Alberto.
The fieldName.oldTime() returns only the value of previous time step. Is it possible to return any specific old time step value like time step 5, 11 .. etc.

Why do you need them?

The old time fields are removed from memory and lost if not written to disk.

If you need them the only way I could think to, is to store them on the disk and to recover them from there
