In v1.3.5, using a file created with SI units (as shown in the attachment), selecting a material from the material library gives the error message shown in the attachment. The material can be selected if the file is created with Imperial units. This error does not occur in v1.3.4.
A second item: The “Zero temperature” value for thermal expansion is not converted to changed units in the material edit or material preview dialog boxes. I have not checked to see if the value is converted in the .inp file.
