I have created a 2D geometry for COMSOL simulation modeling, and I have attached the relevant files for reference. The geometry consists of two squares:

The upper square represents the electrolyte flow domain, with its inlet and outlet indicated in the attached files. The lower square represents the workpiece. Additionally, a circle within the upper square represents the wire. I need assistance with the following aspects:

I have resolved multiple errors encountered during the simulation; however, I am struggling with one final error: "Inverted Mesh Element." Despite my efforts, I have been unable to fix it.

In the simulation, I require tool movement towards the workpiece. I have attempted various solutions, but the tool movement is not occurring as expected.

Furthermore, I would appreciate feedback on whether the selected physics in the simulation are correct. If any modifications are necessary, please provide guidance. I am completely stuck on this issue and have been struggling with it for the past 20 days without success.

I request all viewers to kindly assist me in resolving these problems. I have attached screenshots of the error encountered & physics invoved in the COMSOL simulation file. A reference research paper for better understanding is "Modelling of Wire Electrochemical Micromachining (Wire-ECMM) process for anode shape prediction using finite element method" by Vyom Sharma, Ishan Srivastava, V.K.
