Hello Sim community,

In Physics Results Explorer app:

In an explicit simulation, I want to divide ALLKE by ALLIE. In order to have this ratio and check if it meets a certain criterion - Typically < 0.05 to verify a ~quasi-static assumption. 

But I can't do it in the "XY Plot from expression", as there's a division by 0 probably only due to the first point at t=0. See picture. That makes any division not possible. Right now, what I do is that I add a small number (say 1E-12) to the denominator. Which is not even great, as it may not be such a neglectable value close to t=0 when internal energy is small. 

Isn't there a better way to do this kind of operation? 

In Abaqus CAE, there was even a plugin available to display right away the ratio of energies in % (ALLKE, ALLAE, or ALLSD could be divided by ALLIE if I remember well). Is there a way to automatize it also on the 3Dx platform, as that's a check that's often repeated? 

Thank you,

Regards,

Jimmy
