  Hello,
  I need to obtain the surface area of selected elements. I tried to select few element faces and create named selection.

  Here is a sample command set that you can use to get the area. Make sure you create a named selection with the selected elements. In this case, named selection is called my_elem
  
  /PREP7
  cmsel,s,my_elem esln *get,ncount,node,,count
  my_area=0
  nnum=0
  *do,i,1,ncount,1
  nnum=ndnext(nnum)
  node_area=ARNODE(nnum)
  my_area=my_area+node_area
  *enddo
  area_of_name_selection=my_area
  ALLSEL
  /exit
  
  Example:
  
  After inserting the commands, solve the model. Since there is a /Exit command, solution process will be stopped after executing these commands. You can check the solution information for the area.
  
  In solution information, you can see the unit system being used
  
  For details on these commands, please check the command reference manual: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v212/en/ans_cmd/Hlp_C_CmdTOC.html
