PyLith-2.2.2: Could not find slip rate

Dear PyLith team:

I’m using backslip model to simulate interseismic deformation. I first verified the case with uniform slip-rate on the fault. However, when I attempted to perform a checkerboard test, the code failed with the message: ‘could not find final slip rate at…’. My spatial database of slip-rate fully covers the fault. After that, I changed the interpolation method to “nearest,” but the result was strange.

You can find my files below. Any comments or suggestions would be greatly appreciated.

What is the spatial distirbution of points in the spatial database? Are they uniformly distributed, clustered, other? Are they on a plane, or do they match the geometry of the surface? What data dimension are you using?

My apologies for not being able to respond during the shutdown of the US government.

Thank you for your reply! Sorry for the late update. I have resolved it by changing simplegriddb to simpledb. Appreciate your kind help all the time.
