This behaviour is not supposed to have changed. The basic mechanism is implemented in CactusBase/IOUtil, where the aliased function IO_TruncateOutputFiles decides whether to truncate (overwrite) or not. Of course, each thorn is supposed to contain logic on top of this to ensure that this function is only called once, during the beginning, so that things are not overwritten at every time step...
This function basically determines whether this run started from scratch or whether it is a restart.
Which thorn is misbehaving?

Hi,
I am wondering if the default behavior of Cactus output has been changed recently. When starting a simulation from scratch (i.e. no recovery), already existing output files used to get overwritten. Instead now, Cactus appends data to the end of the files. How can I change this behavior? Is there a parameter for this?
