When use PDD,it shows cannot convert 'mm day-1' to 'kg m-2 second-1' about pism HOT 4 CLOSED

mm day-1 cannot be converted to kg m-2 second-1 because they are not compatible: one needs to multiply mm day-1 (a rate) with a density. If your input is in mm day-1 water equivalent, assume a density of 1000 kg m-3 and you can just change the unit attribute in the input file to kg m-2 day-1 (a mass flux through an area).

Please re-open this issue if it is still a problem.

thank you,if this is changed in pism2.0? because when i used the script from others(use version 0.7), the unit in the input file is mm day-1.

@zyastc213 This change was introduced in PISM 1.0, i.e. in the next release after 0.7.
