The stiffness of gas given by the ideal gas law pV = nRT can be considered in the nonlinear dynamic analysis.
The calculation of gas is available for accelerograms and time diagrams for both the explicit analysis and the nonlinear implicit Newmark analysis. To determine the gas behaviour correctly, at least two FE layers for gas solids should be defined.
- How can I additionally model welds for the connection of two surfaces with a contact solid?
- How can I deduce the axial stress and hoop stress of a circular container?
- How is it possible to consider the real cross-section geometry of member elements in RWIND Simulation?
- When calculating a connection using the FRAME‑JOINT Pro add-on module, a message appears sayng that the value is out of the valid range (existing value: 160, minimum value 200). What does this message mean?
- I have calculated a box beam. Which surface results or surface stresses can I use to evaluate the buckling behavior of the web plates?
- Why do I get large differences for the design of a longitudinally stiffened buckling panel in comparison with the German and Austrian National Annex?
- How are the signs for the release results of a line release and line hinges interpreted?
- How can I create a curved or arched section?
- After the calculation in the RF‑/DYNAM Pro - Equivalent Loads add-on module, the size of my file has increased significantly. The performance has worsened enormously. What could be the reason for this?
- Is it possible to manually specify a longitudinal reinforcement for design in RF‑PUNCH Pro?
