Good evening everyone,
My model looks like this (picture forum2). I have a bonding wire attached to a surface (plate) (typical bonding connection in a semiconductor). There are two contact points. At these contact points I let locally over the parameter set of ANSYS the net become finer and finer, in order to receive a convergence in my results. 

I have read in literature that there is a method to compare averaged simulation results with non-averaged simulation results. If these results do not differ much, the mesh is ok and can be used. I can do this in ANSYS under solution in the left tree. 
Now to my question.
Can I compare the averaged simulation results with the non-averaged simulation results in ANSYS or in another way (picture Forum1)? Not graphically, but as numbers, if they match or have deviations.

Are there other ways than the mesh study to evaluate his results from the simulation if the mesh created is ok?

Hi Patrik,

You are right and it is best to compare averaged and un-averaged values. Please note that in some cases convergence might not be possible. You can check the lesson below where this topic is described in detail:

Specifying an Appropriate Element Size for Stress Analysis — Lesson 1 – ANSYS Innovation Courses

After watching the video above, check if adaptive convergence is of interest to you:

Hi Abedini,

thank you. I wanted to solve it more complicated via Excel but Ansys does that itself. 

 

Is there a way to perform the convergence as seen in the second link for a thermal-electrical analysis?

I do not find this possibility in the thermal-electrical analysis.

Hi Pratik,

I see your point. I'm not familiar with electrical analysis but perhaps you can also post your question in the corresponding channel within this forum.
