Why the pressure calculated in a transversal of a sound soft boundary is not zero?

Please login with a confirmed email address before reporting spam

I made a study by pressure acoustic module with a sound soft boundary whose equation show the pressure is zero,but then when I made a postprocessing,I found the pressure calculated in a transversal of a sound soft boundary is not zero(also very close to zero) but a order of magnitude 10e-20. I wonder if it is right as a resonable calculation error?
