The article describes the technique of resource-intensive (in terms of computing resources) and accurate assessment of the thermal mode of electron-ic equipment. The method involves the consist use of software packages “AN-SYS” and “ASONIKA–TM” to calculate temperature pattern that occurs dur-ing operation of the device. Accounting result in “ANSYS” is used as a thermal boundary condition of the first kind for the calculation in “ASONIKA–TM”

The article is an overview of the problem of providing the thermal regime of radio-electronic equipment of launch vehicles and describes the need to develop a method of resource-intensive (from the point of view of computing resources) and accurate assessment of the thermal regime of radio-electronic equipment. The method involves the use of the finite element method and is a sequential use of the software packages "ANSYS" and "ASONIKA-TM" for calculating the temperature field that occurs during operation of the device
