Shell offset can be introduced to the mesh by means of a command snippet that is inserted under a surface body. For example: !################################################################### ! Commands inserted into this file will be executed just after material definitions in /PREP7. ! The material number for this body is equal to the parameter “matid”. ! Active UNIT system in Workbench when this object was created: Metric (mm, kg, N, C, s) esel,s,mat,,matid sectype,matid,shell,, secdata, 1.0,matid,0.0,3 ! thickness = 1.0 mm in this example secoffset,TOP emodif,all,secnum,matid allsel !################################################################### Even though the offset is applied in the ANSYS solution, WB plots do not show the offset. You can visually verify the offset by going into the ANSYS environment, selecting only the Shell181 elements, and plotting the shells with element shape turned on.
