Hi fellas,

I have several material defined in Engineering Data. In workbench Mechanical, how can I assign material to parts using APDL commands instead of choosing from the material section? I assume I have to insert a command under the geometry and use matID, but don't know how to write the command. Any help is appriciated :)

Hi

The commands to look at are, MP, etc.

So to define material properties needed for structural analysis we need at least the three commands, that can be added in a command snippet under a part:

MP,EX,MATID,200E9          ! Define Elasticity Modulus

 

MP,NUXY,MATID,0.3           ! Define Poisson’s ratio     

MP,DENS,MATID,7800       ! Density

All the best

Erik

Thanks Erik. Is there a way to only link the part with the material definition in Engineering Data rather than defining individual properties? As in like assign 'material 2' definition to 'geometry 1' using commands?

Hey there,

To assign materials to parts in Workbench Mechanical using APDL commands, you can indeed use the MATID command under the geometry. Here's an example command:

! Assuming your material ID is 1 and part number is 2
MP, EX, 1, 2, Youngs_Modulus, Poissons_Ratio

Replace Youngs_Modulus and Poissons_Ratio with the appropriate numerical values for your material. This command sets the material properties (Young's Modulus and Poisson's Ratio) for material ID 1 assigned to part 2.

Remember to replace the placeholder values with your specific material properties and devops course part numbers.

Hope this helps!
