A new version of the Fidesis 6.1 package has been released, even more user-friendly and more functional.

Additions and improvements to the functionality

  • RBE3 interpolation connections are a special type of connections that allows you to distribute loads and boundary conditions on the model without adding additional rigidity to the connection of the connected region.
  • The possibility of re-emission has been added - the functional allows us to take into account the effect of absorption of thermal energy of radiation by bodies, which increases the accuracy of thermal calculations using the boundary condition "radiation".
  • Added the assignment of the Mohr-Coulomb plastic model - a material model used for calculating soils, which allows you to more accurately calculate some types of soils when analyzing taking into account plasticity.
  • The list of available calculations for axisymmetric problems has been expanded - the functionality of the solver has been expanded when solving axisymmetric problems in a 2D formulation. Added the ability to calculate natural oscillation frequencies. Added support for nonlinear calculations taking into account plasticity and large deformations. Added the ability to solve dynamics problems. Added the ability to solve problems of thermal conductivity.
  • Improved performance in explicit dynamics problems - increased the speed of solving dynamics problems using an explicit time integration scheme, which makes it possible to more effectively solve problems of high–speed interaction - problems of shocks, explosions, wave propagation in an elastic medium, etc.
  • The list of editable properties in the Preprocessor Tree has been expanded by adding the ability to edit a number of model properties through the properties page. Now there is no need to use the command bar to change properties and names for blocks, contacts, periodic conditions, as well as for beam sections and shell layers
  • The "Coordinate Systems" filter has been improved - the ability to view results for individual layers of multilayer shells in local coordinate systems has been added.
