charge conservation not recognizing epsilonr_iso as epsilonr

Hi, I am getting an error from my study with the electrostatics module that is "Undefined material property 'epsilonr' required by Charge Conservation 1." In my materials, I have added a Relative Permittivity property but that autopopulated the variable name as epsilonr_iso because the permittivity is isotropic. I cannot find a way to change or add an alias name of the property, or get the charge conservation to recognize epsilonr_iso as the permittivity (I've already selected Relative permittivity: From material). How can I address this issue? Thank you

Hi Lulu,

It looks like the issue is that you have not assigned any material properties to domain 3. Perhaps you meant to assign it the Ta material?

Best,

Jeff
