I'm attaching a simple file that uses AdamsBDF to solve a spring/mass motion problem. I added units to everything and it worked perfectly, but then I added an "if" statement that generates a ramp function and tried to use it in the D(t,X) matrix and I get a units error even though the ramp function spits out Newtons.
You can reproduce the above by toggling which F(t) is disabled or enabled.
If you want to look at the file (Prime 3.0 format) and provide feedback, I would appreciate it!
Mathcad is complaining that you are comparing t (second) against scalars. See fix below.
