Hi,

I want to simulate the attenuation of electromagnetic waves after penetrating very thin silver. The thickness of the metal is 80nm and the length and width are 2mm,While running the simulation, I am getting following errors:

 [warning] Model Resolution has caused significant changes in object dimensions or contact between objects. Please compare the MRL set on the bodies with the dimensions of the bodies. Please ensure the units are selected such that the smallest critical features of the model are at least 0.001 units long. Specific details may be found in Modeler>Model Analysis>Show Analysis Dialog>Last Simulation Mesh.

  [warning] Model has very thin thickness body

  [error] Surface Mesh Generation Failed.

  [error] Simulation completed with execution error on server: Local Machine.

Is there any solution? Secondly, someone has proposed to reduce the size of the model, but my simulation results can not match the measured results. Is there a better way?

Thanks！

Please provide more inputs of your issue to help us serve you better.
Please change the units to "micrometers" if not already done and try to simulate the model.
You can also refer to "model resolution length" section in the HFSS help document for more details on "MRL".
Otherwise you can use layered impedance boundary for your case.
All the very best.
