Hi, I have been attempting to create a new datarray of type =UInt64 using the calculator filter but failed. Even choosing Unsigned Long as Result Array Type in the filter results in a dataarray of type UInt32. On the other hand, chosing Id Type results in dataarray of type Int64 but not UInt64. Is there any possibility to export a data array from ParaView as type UInt64? I am aware of the opportunity to change the type manually in the resulting vtu files, but this is not a very elegant solution.
