I am getting the error of "Operation cannot be performed with units but I redefined the values with new variable names which has no unit but I am still getting the same error. I need suggestions to resolve this issue. I have attached the Smath file and a screen shot of the same.

Thanks !

Post the file.

What is this a calc of? Do you have a good known example to check against?

Check your operations- calcs dependent on variables need to be below or to the right.

Your units are goofy. break out a pencil and paper and do the dimensional analysis to see how your calc is working, or really not working. SMath is REALLY good at keeping track of units. it is doing exactly what you are telling it to do.

Seems that tanh(x) returns a "number above the max" error if x > 354, a "division by 0" error if x < -228 (reported as BUG SS-2284)



About the units, the tanh argument must be dimensionless; m*Lc can't be dimensionless because m is not the inverse of a length (your definition of m contains the Boltzmann constant and 2 lengths)

Hello.

I've fixed this issue and here is corrected SMath.Math.Numeric.dll SMath.Math.Numeric.dll.7z (25 KiB) downloaded 133 time(s).
Please put it into installation directory of SMath Studio.

Fix will be included into new version of the program.

Regards.
