I am trying to run a Free Tetrahedral mesh on a project I've designed. However, when I attempt to add a distribution to the simulation, it refuses to and gives a pop-up error of "Empty Expression."

Any idea why it is doing that? Thanks.

Hi
Normally that means an required entry is all empty (normally you leave a "0" or a "1" or something relevant in ALL model tree field entries).
Or it means you have forgotten to define the Entities on to which your Distribution applies, these are different (or might be) from the ones of the main mesh node

Good luck
