Hi
I have tried to define the lattice constant under crystal properties- lattice dimensions
but when I click ok, the pop up window says unknown variable. Then I tried to define the variable under variables and functions. I assigned the variable name – lattice constant, expression -a but unable to assign value to it.
I wanted to know where am i doing it wrong?
