COMSOL expression evaluation
Hi all,
In COMSOL I am using two expressions to calculate a certain parameter, and the objective is to pick the one that under given conditions gives a result, which is a real number and 0<=x<=1). I can easily plug a MATLAB routine to do the assesment and pick the value calculated from either of the two expressions, but I always consider the use of MATLAB from COMSOL as last resort, so maybe there is a way to do it with some smart formula in COMSOL?
Any help will be very much appreciated,
Mike

Mike,
you could try to use boolean expressions, like
x*(x>=0 & x<=1) This would result in the value of x between 0 and 1 and 0 elsewhere.
Cheers
