Can we change the relative amount in the system tab in DPD caluation?

Dear All,

In MesoDyn, when restarting the calculation, we can conrol the relative amount (i.e., the composition of the simulation cell).

Is this possible in DPD calculation?

I tried it but the relative amount in DPD calculation tab seems not to be controlled.

If impossible in DPD calculation tab, is there any other tip to do this?

Thanks in advance!!

Best regards
