Analysis - Empty Coil - Grid Fail

Hello,
I followed all the procedures in the Analysis - Empty Coil correctly but the grid could not be created. What is the likely problem ? thanks

Hello,
Do you have any error message appearing in the console?
If a grid cannot be created, you have to carefully check the grid settings, and ensure that the number of cells is not the big (if so, you can reduce it by adjusting the padding, for example).
