    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

try i.phys.normalForce.dot(i.geom.normal)
The dot product of a vector "F" and unit vector "n" is a projection of F on the direction of n, i.e. the "oriented length" in the "n" direction.
The magnitude should be the same as i.phys.normalForce.norm(), but you can distinguish tension/compression based on the sign of the dot product.

cheers
Jan
