COMSOL: Simulation of liquid nitrogen cooling (Help please)

In summary, a 10x10x0.5 mm InSb sample is attached to a cooled copper table with silver glue, while liquid nitrogen passes through the table. The sample is exposed to a beam of electrons, causing the surface to heat up at a temperature of 300 K and a pressure of 1 bar. The COMSOL modules used for simulations include heat transfer in solids, laminar flow, and multyphysics. However, it is not possible to calculate the heating during cooling. A nitrogen dynamic viscosity of 161,4 E-6 (Pa*s) is also mentioned. The conversation then moves on to simulations of heating with COMSOL, specifically for LN2, and it seems that the simulation was

TL;DR Summary
Simulation of electron beam heating (SEM) of an InSb sample with nitrogen cooling. It is not possible to calculate the heating during cooling in COMSOL. Maybe I'm using the wrong modules for cooling? Without cooling, the heating counts correctly.
The InSb sample (parameters 10x10x0.5 mm) is glued with silver glue to a cooled copper table. Liquid nitrogen passes through the table. While the model is at a temperature of 300 K and at a normal pressure of 1 bar. The sample is affected by a beam of electrons, which causes the surface to heat up. Modules used in COMSOL:
1. Heat transfer in Solids
2. Laminar Flow
3. Multyphysics (auto)
It is not possible to calculate the heating during cooling. Nitrogen Dynamic Viscosity - 161,4 E-6 (Pa*s)

Good afternoon! Yes, it seems that everything turned out on a more powerful computer.
