Hi,

I would like to ask how can I define the material properties for many elements in one apdl command in Ansys workbench.

The constructed model contains three different materials. One of them contains about 200 elements modeled using solid65 elements. These 200 elements have the same material properties. I defined the material properties (elastic modulus, Poisson's ratio, tension stress, etc.) by adding an ADPL command for each element (Image bellow), then I paste the code that contained the material properties. This operation takes a long time to define the material properties for each element (about 200 repetitions).

I would like to ask, how can I define the material properties for 200 elements in a single APDL command without doing the 200's repetition.

Create a named selection with all the bodies for which you need to assign the material
For example: named selection is called my_bodies
You can use commands similar to this under the analysis branch(static structural, modal etc)
/Prep7
cmsel,s,my_bodies
!define your material using the MP commands
emodif,all,mat,100 !where 100 is material number
allsel
/solu
For more details on these commands, check the command reference manual Command Reference (ansys.com)

Hello Govindan, i am facing a similar problem to define the material properties using command. May I ask what the material number 100 refers to. Is it a random number i have to assign?
