I was running a magnetostatic simulation. I checked the model first before running. It said :Verify conduction path: Conduction path validate success.

However, after I ran the simulation, it finished with error:

"For any conductor path, the current flowing in must be equal to the current flowing out.

Simulation completed with execution error on server. Local machine. "

Any hints will be appreciate. Thank you.

Hi @Tryphena How did you set up your current excitation?
If you are using an open busbar that terminates on the sides of the region, verify that the direction of current is "in" and "out" on the two terminals.
In Maxwell 3D, you must always provide a complete path for current to flow, either in a closed conducting loop or by entering and exiting the region wall.Current cannot flow into the air region.
Also, If you are using a coil, make sure there is a physical gap or insulation boundary between turnsto prevent them from shorting out.
If this did not work. Please share some screenshots of the model and excitation to interpret the problem correctly.

Hi @nchode Thank you for your detailed answer. I am not working on coils. I am working on a structure has small features. I have run the model again in a more powerful computer. It has a warning: Critical features could not be preserved correctly. Error: Surface Mesh Generation Failed.
I guess the previous simulation may not finished all the way with the error of conduction path....
I am trying to refine the mesh to see if this solve the problem...
