Anyone can provide suggestions. 1. The extension does not take effect in direct and adjoint, but only in the calculation of the baseflow. The meaning is that the dat grids of direct and adjoint are not encrypted according to the settings in the extension.Set as follows <EXPANSIONS> <E COMPOSITE="C[37]" NUMMODES="3, 3" BASISTYPE="Modified_A,Modified_A" POINTSTYPE="GaussLobattoLegendre,GaussLobattoLegendre" NUMPOINTS="4,4" FIELDS="u,v" /> <E COMPOSITE="C[37]" NUMMODES="2, 2" BASISTYPE="Modified_A,Modified_A" POINTSTYPE="GaussLobattoLegendre,GaussLobattoLegendre" NUMPOINTS="4,4" FIELDS="p" /> </EXPANSIONS> 2. The vorticity and modal plots in tecplot are very blurry. Do I need to perform additional post-processing on the results (such as C0Projection) or increase the grid order for recalculation? Ben
