some problem about the timeVaryingMappedFixedValue;
 

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?

Sincerely
Tang
