ERROR check_data_30.f:295 Unphysical field variables detected on one or more processes

Hello everyone
I am a student just starting to use MFiX, and use MFiX19.3.0 for calculation on Ubuntu system. My model is a regular hexagonal tube with particles falling from above. But whether I use the GUI to build the DMP solver (Figure 1) or calculate it through the terminal (Figure 2), the same error always occurs.

The previous method on the forum did not solve my problem. After I added the definition of the left and right boundaries of the calculation domain, I got the error shown in Figure 3. I hope someone can help me.

The compressed file is my model.

thank you all.
