When I try to apply a material in a thermal study I get an error message similar to this and cannot apply any material:
Modification of a ****** thermal element, the isotropic/orthotropic has not been specified
(*translated*, my version is in french... (sim mechanical 2013))
No matter what type of element I used, or what type of material model (iso, ortho, iso temp dependent...) I apply in the element definition I always get the same error. Even in a blank study with no geometry in it, when I create a component, select the element type and def, and try to apply a material I get this message error. This only happens in thermal studies, first time trying to use thermal studies...
Seems like the software cannot read the material model from the element definition. I tried reinstalling the software and still get the same message.
Solved! Go to Solution.
I agree with your thought: sounds like the software is not able to read the element definition. What happens if you do this test?
- Define the element type to be brick.
- Edit the Element Definition and set the material model to Orthotropic.
- Click OK to close the Element Definition.
- Edit the Element Definition again. Is the material model set to Ortho?
If it is Isotropic -- the default -- this would support the idea that the software is not able to read the Element Definition. In this case, try saving the model to another folder where you have successfully worked on other models, or save it to a really short folder and filename, such as C:\junk\test.fem. (Everyone needs a junk folder, right?)
Also, I see that you have version 2013. Have you installed service pack 1 and/or 2? I do not recall any problems like this that the service pack would have fixed.

Hi, i have the problem with my installation.
My study i steady state heat transfer.
When i edit material, the library give me an message that the material is not isotrop.
Would you like to help me.
