How to assign material data to multiple components in APDL

  Hi all,
  
  How to assign material data to multiple components in APDL. When I try to add "real constant" APDL says "Please check and change keyopt settings for element.......".
  
  Does the "real constant" define the material data for separate objects?
  
  Thank you.
  
  BR,

  Say you have defined two material properties via MP,EX,1,200E9 (material ID 1) and MP,EX,2,100E9 (material ID 2).
  
  Before meshing a volume say with vmesh, or an area with the amesh command then one specifies which material ID nr to use (that is which material property).
  
  So one would say mat,1 and vmesh,all to use the first material and mat,2 and vmesh,all to use the second material.
  
  So the command mat decides which material is to be used when meshing.
  
  As in the help manual it "sets the element material attribute pointer", thus "assigns this material number to the subsequently defined elements".
  
  The example above assumes that we are about to create the mesh.
  
  It is also possible to create the mesh and then change the material properties of a part or some elements.
  
  This is done via MPCHG, which works as follows:
  
  Select all the elements that you want to change the properties
  
  then use say to change to property 2 material: MPCHG,2,ALL
