The article discusses the use of the finite element method in medicine. Finite element analysis has existed for a long time, and its application can cover vast areas of various fields. Using this technique in medicine is not new, but there are some problems that still have to be solved. In the work Finite Element Analysis or Method is explained. Briefly explained the application of the tool in the fields not related to medicine. A literature review is conducted on the use of Finite Element Analysis in medicine. The usage of the technique in dentistry is covered. Disadvantages and advantages of the use of the Finite Element Analysis tool in dentistry is presented in the work.

The work was written to outline important steps of numerical analysis. This work presented the guidance to perform any analysis in the engineering design tools. At present, software tools are used in every field, and hence, it is essential to understand some techniques to utilize them. The following work gives guidance from the modeling of a given structure to the applying boundary conditions to it for further analysis. 3D modeling, the appliance of material contacts, constraints, loads and mesh are outlined in this work. Also, the work provides postprocessing guidance. For instance, the use of Sensitive Analysis tool to shorten the time during numerical analysis.

This work is focused on the comparison of two software packages Solidworks and Inventor. The following two software packages are well known for their ability to design and they share a leading position in the market. A comparison of the functionality of the two software packages will be made. The difference will be outlined on the divorce tools they have. The market share of CAD software packages will also be briefly outlined. Both software packages will then be compared for how easy they are to use for customers. Lastly, the availabilities of the following software will be discussed.

Increasing the raw materials deep processing efficiency for commercial fish farming, including freshwater fish caviar of the carp family that demonstrates low demand on the Russian market, is an important and urgent task. In the modern context, Russian food industry needs high quality natural emulsifiers, for example, lecithin. The research aim is to determine the thermophysical characteristics, cryoscopic temperature, refrigeration object density and the amount of frozen moisture in it, depending on its temperature variation. The study object is carp caviar. A man found the temperature variation during carp caviar freezing using an experimental stand, containing a specialized ThermoChart program for constructing thermograms. The authors determined caviar material density dependence on its temperature in the range from −18 to 5 °C: with an increase in temperature, its density raised to 1,071 kg/m³ monotonously at Tcr = −0.91 °C and then changed up to 5 °C ordinary. An obtained thermophysical characteristics values analysis of carp caviar, which is a high-moisture product, demonstrates that its freezing is accompanied by the latent crystallization heat release, depending on a decrease in the study object temperature and due to the proton bonds presence at the sample microlevel. A man can use obtained data in the freezing processes calculation and refrigeration equipment design; and utilize the semi-finished product to extract lecithin.
