We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Thanks for your help.

instead of using delta_uz_11/dt (dW(x,y,z,t)/dt), why don't use VZ(11)? 

And also can use TAN(ROTX(11)) instead of delta_uz_11/delta_ux_11 for dW(x,y,z,t)/dx?

Note W(x,y,z,t) is the displacement of nodes in z direction in current time t.
