Hi All,

We are using the CST Studio Suite  from last three years for ESD and EMC simulation. Recently we updated the CST studio with 2024 suite. When we are simulating one of our design for ESD and found the below differences.

• Difference with the ESD simulation surface current with CST studio suite 2024, when compared with suite 2022 (design is same).

• The ESD discharge current path is not similar in 2022 and 2024 suites.

Simulation with Suite 2024:

Simulation with Suite 2022:

Could you please look into this issue.

Your early response will be appreciated.

Thanks and Regards
