Hi,

I am trying to simulate a thermal ablation, where the antenna and tissue is touching each other. I am getting  ERROR 3848: Wrong specification of the medium for a wire segment.

However, when I set up the antenna and tissue apart I am not getting the error. As I understand this error occurs when meshing 2 touching objects with different materials. I am not sure how to fix it. Any help is much appreciated

 

Thanks

    You should be able to overcome the error by performing a UNION on all the objects that are touching (if two or more objects are touching each other, you need to union them irrespective of the material properties). Check the media properties of the faces and regions after the union to make sure they are right.

    Thank you very much.  I made it a UNION and it works fine now
