Hello Aeron, Another way to map data in APDL is with the mapping processor. Here is a set of example commands: /map ! Enter the /MAP module (writes out a BeforeMapping.db) target, PressureMapSurfs ! Use named selection pressure_faces as target nodes ftype,csv,0 ! type of pressure file to be mapped (csv file ) - real component only read,FileOfData2Map.csv,1,,2,3,4,5, ! read pressure data file plgeom ! Plot geometry - I think this yields a point cloud of the mapping points map,,2,,1, ! Map 2D surface data - linear interpolation plmap,target,,,0 ! Plot mapped target pressure - real part writemap,MappedData.dat ! Write mapped pressure in SFE command format Please note the map processor alters your databse. So once you are finished mapping you need to resume from BeforeMapping.db.
