help internal parser error

Hi,
it appears an error that says "internal parser error" when I write " 0.01[Pa·s] " in Global Definitions->Parameters.
It has something to do with the viscosity units.
Could anyone help me?
Thanks in advance,
Belén

I got the same general "Internal parser error" message when trying to plot an interpolation function, with function value units specified as J/(kg·K) (which I must have copied from some COMSOL generated results). It took me quite some time to realize that the only problem with this function is the dot used in the units specification. After changing it to J/(kg*K), everything was fine.

Could this error message be made more specific?
Or does it always indicate an illegal units input?

Thanks,
Miroslav

Hi

yo uare probably right the * and the . are two different characters (ASCII Codes), so it could be that the equation parser does not understand the dot"

Good luck
