However, I am finding that the calculated currents through the contacts are drastically different in CHARGE and HEAT, despite using the same configuration and simulation region. I&#8217;ve looked through the Lumerical documentation and all of the CHARGE \/ HEAT simulation settings, but cannot seem to find the source of the mismatch. Below is a screenshot of the simulation setup:&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/01\/15-01-2025-1736959605-mceclip2.png\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Below is the current found through one of the aluminum contacts in CHARGE:&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/01\/15-01-2025-1736959585-mceclip1.png\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;And below is the current calculated through the same contact in HEAT:&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/01\/15-01-2025-1736959690-mceclip3.png\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;I would appreciate any kind of support on this.
