Hello everyone

I have some trouble when I use BC timeVaryingMappedFixedValue.
The timeVaryingMappedFixedValue BC will triangulate the inlet face and using the Linear interpolation to interpolate the inflow data to the center of the cell.
I have two cases.One of case the inlet face is unstructured grid(triangle) and another case the inlet face is structure grid(rectangle).Both of cases the resolution of the grids are same.But I find the inlet face interpolation result have huge difference and then make my final result has huge difference.So I think because the grid type of the inlet face is different,So the interpolation result become so different.
So My quesion is:
1. how to modify the unstructured grid system? Because i check the result of my structure grid case and the result looks like correct.But the unstructure grid case is bad.If I need to increase the resolution of my unstructured grids(decrease the size of the grid) to make the interpolate result become better?Or If there are any method can solve this problem?
