Hi, I have a look at R19 capability and find AIM have capability of setting anisotropic material property but there was no results when creating a new material in AIM. Therefore, how to set anisotropic material property in AIM?   Thank you.

Hello Kin

I am checking this option and will update you.

Hello Kin

Discovery AIM does not support anisotropic material properties. What you are seeing in the capabilities chart seems to be a typo.

Hi, Naresh Since AIM can't use isotropic material, I have further questions as below. A). Can AIM use orthotropic material? I tried to find orthotropic material but there was nothing appearing. B).And is it possible to use MAPDL command to defined either isotropic or orthotropic material in AIM? If yes, how can I do that?   Please help me confirm these two questions, thank you.

Kin  You can add orthotropic properties and temperature dependent properties via a user command:

Naresh Patre  I've tried user commands shown as attached pictures but it didn't work. The results of displacements (and stresses) of three directional forces I applied to the model respectively is the same. Did I input the data incorrectly? or something I missed? even or AIM can't do it? So, I'd like to be sure about that" can AIM do orthotropic material for sure? " Thank you.

Kin It seems the material ID 1 that you are defining is not associated with the body. As a workaround, you can define a new material ID by creating Selection Set and then use this ID for defining orthographic material properties. Please check out the attached example and the user commands defined in this example.

Thank you for this solution. It's the material ID problem and it works after changing material ID.

Hi,

How can I use the solver Command to define orthotropic conductivity in thermal analysis. I am new to it, and I don't know how to define it, thank you.
