>> Hi, Neks!<br style="font-family: Arial, Tahoma, Verdana, sans-serif;" /><br style="font-family: Arial, Tahoma, Verdana, sans-serif;" />I am working with a complex geometry which was built in gambit. I have a velocity fields for my grid. But I want to interpolate these velocity fields to a new grid. The old grid was changed without moving the geometry parameters, I just changed the position of the computational nodes and reduced their number (see pictures old_grid and new_grid *). Interpolation ends as usual. The velocity field is interpolated perfectly, but the pressure field is not interpolated correctly (see pictures pressure_field_before_interpolation and pressure_field_after_interpolation **).
>> Tell me, what is my mistake? Is it possible to interpolate from a larger number of nodes to a smaller number of nodes?
