Is it possible to analyze the effects of an hermetically sealed object with RFEM?


To analyze a gas-tight object, it must first be modeled in RFEM. Then, you can create a new solid from the boundary surfaces. In this mode, it is necessary to enter the variable “Gas” as the solid type whereby it must have a material of the same name (see Figure 01). In the “Gas” tab (see Figure 02), you can define additional gas parameters. As a result, the resulting gas pressure, the overpressure and the initial pressure can be graphically displayed for the gas volume. Furthermore, the Result Navigator provides the deformed volume of the gas as well as its temperature.
