Dear STKO team,

I would like to use the face mass condition to assign a value of load depending on the z-coordinate. I want the load to be -392.4 when the z-coordinate is equal to -100 and take a value according to the following equation when z>-100:
-9.81*0.707*(-60-z). I have tried the following but I am not sure if it works properly:

-392.4*(z==-100) -9.81*0.707*(-60-z)*(z>-100)

Any help will be appreciated.

Thank you!

First, for a load you have to use the FaceForce, not the FaceMass.
That being said, you should provide a graph of the function you want, otherwise we cannot tell you if that function is fine or not

Hello,

Sorry for my oversight. I wanted to apply a face load. The equation that I want to have is:

-392.4*(z==-100) -9.81*0.707*(-60-z)*(z>-100)

The graphic representation is shown in the attachment.

Thank you.

In this case this is not fine: This means:
-392.4 If Z is exactly -100, -9.81*0.707*(-60-z) if Z > -100, 0 otherwise

You can do this:
