Dear Alexander, Many thanks for this comment. We will have to go and have a closer look at the interpreter to see what is going on here. I do not suppose I could ask you to register this as an issue? Sorry we have been slow to respond. I am afraid we have had quite a few distractions recently. Best regards, Spencer.

Hello,

I calculated a boundary condition

<D VAR="u" VALUE="-y^2+1.0" />

and had found that the expression "-y^2+1.0" had calculated as "(-y)^2+1.0". The "1-y^2" and the "-(y^2)+1.0" are OK.
