problem with running multi quantum well in atlas silvaco

[niloofar]

hi every body

i am simulating multi quantum well structure by atlas and the sizes are about Angstrom but my simulation cant show wavefunction in this structure
and when i change the sizes to nanometer it becomes better!!!

Also the statement SOLVE VCATHODE dont work and answers are the same az simulation with only SOLVE INIT !!!!

I really need help, would you please help me?

it is my infile:

go atlas
