How to set customized grid mesh in Honeybee

Dear All, I have a question regarding how to setup customized grid to compare with field measured data.

I have tried two methods but neither works: 1) use "moveTesMesh by setting 0.3, 0.7,0 to move the testmesh; 2) establish a new mesh surface and set that surface as geometry and try to generate the grid data in the new surface. But neither method works. Does anyone have an idea of how to set the custmized grid?

Thanks a lot.
