Hi Everyone,
I want to create some variables using log () ; but it gave me the message "unexpected unit of input".
Although the unit of the used variable is meter.
My physics is "Solid mechanics";
My study is "Stationary";
Did anyone know how can I solve this problem?
Thank you in advance,

I'm guessing that the problem is that you are trying to take the logarithm of a quantity that has units. The input quantity to a logarithm should be a unit-less number. If you want to take the logarithm of the number of meters, then you could try dividing it by 1.0[m] first, so as to get rid of the units.

Hi
using the version 5.2, in the variable expression i try to use sinh(phi) or cosh(phi) and give them a name , the unit of (phi) is the volt wich is the variable of electrostatic module, but the color is orange and show ''unexpected unit of input'' so i can't use it in boundary condition ad i can't solve my problem
Appreciate much for your help!!
