Hello everyone, I am encountering an error when I am doing the SET QUANTITY in postnek. I have 3 passive scalars, and in the SET QUANTITY, I should get them as PS 1, PS 2 and PS 3. Instead I am getting I, E E E, E E E --- these kind of notations. When I try to set either one of them as my Quantity I end up with nothing. Also the Postnek window has E E E E E E...I on top of it, which I have never seen before. I think it's some sort of an error. Has anyone else encountered this? Thanks, Saikat.
