Abaqus export for fluid zones
Presently it isn't possible to export pressure data in ABAQUS format on a face zone adjacent to a fluid zone. Following workaround could be used.
Export the pressure force in ASCII format and in abaqus format(note that in abaqus format zero pressures are written). Then through a simple C program, copy pressure forces from ASCII file to abaqus file taking the advantage of node numbering being same in both the formats.
