SECTIONS: Interface / Model editing / Saving / Loading

1. The mechanism for loading/saving the calculation model has been improved. Significantly (up to 100 times) increased speed when working with HDD drives.
2. An option has been added to save calculation parameters, which will allow you to automatically save all settings made by the user when starting a calculation.
3. A new form of model storage has been implemented. When saving the model, a folder named “modelname_files” will be created. All settings files, a calculation log and a file with calculation results will be stored in this folder.
4. For quick file exchange, the ability to save/load an archive of the calculation model in *.zip format has been implemented.
5. The “Select Elements” command has been improved. Now you can also select elements by index.
6. Added a dynamic filter for selecting design model elements (nodes, rods, plates, solid FE). To activate it, you need to
   press Shift + RMB on a free space in the working field.    
7. The list of filters of the type required to display the numbers of nodes/elements on the model has been expanded. They are convenient to use in conjunction with the “Element Information” dialog and the “Loads” section when viewing results, as well as with the “Select elements by index” command.
8. Information about the time it took the calculation algorithm to solve the problem was added to the log file.
9. A new operation “Model transfer” has been added (main menu “Tools” - “Additional operations”). It recalculates the position of the structural nodes relative to the base one. In this case, additional loads are recalculated: wind loads, wind pulsations, angular acceleration and speed.
10. The functionality of the “Loads” dialog has been expanded:
    - when you hover the cursor over a load, a hint with the number of loads is shown;
    - added the “Create a copy” button.
11. The functionality of the “Layers” dialog has been expanded:
    - when you hover the cursor over a layer, a hint with the number of elements is shown;
    -Added the “Delete layer and all elements” button.
12. In the “Program Settings” tree, in the “Units of Change” section, the ability to set a consistent system of units (“System Selection”) has been added. When you select a system, all units of measurement change at once.
13. A new expanded menu has appeared for working with the “Connections” section
    in the “Calculation model” tree.
14. The functionality of the program has been expanded when importing STL format files. Now you can distribute FEs that fall inside and/or are outside the imported shell into layers.

1. SECTIONS: Loads / Impacts / Calculations
2. Calculation of inertial unloading. To use it, you need to create an “Inertial unloading” object in the model tree. It indicates the node relative to which it is necessary to balance the system of forces and the directions in which this is necessary. The log displays information about the calculated acceleration for each selected direction and the value of the balancing force. It is taken into account for all load cases as a “fulcrum point”.
3. Added a new type of load on the finite element “Temperature load”. Can be specified for bars, plates and volumetric elements.
4. Added a new load type “Total moment” in the “Calculation model” tree. The moment can be specified on nodes, rods, plates, volumetric elements and their faces.
5. New features within the framework of harmonic analysis (HA) of structures:
   - A constant type of damping, independent of frequency, has been introduced;
   - Added the ability to control the damping of elastic elements of the “elastic connection” type, as well as “elastic support” and “elastic base”;
   - The range of frequency loads for various types of kinematic influences has been expanded.
   - Added input of necessary settings;
   - Control of visualization of GA results has been moved from the dialog to the “Calculation model” tree.
6. A new way to specify loads in the “Calculation model” tree. Loads can now be specified in tabular form, which allows the import/export of numerical data via text files.
7. In the current version, in the “Calculation model” tree it becomes possible to have several objects of the type “Linear static analysis”, “Nonlinear static analysis”, “Dynamic analysis”. Load cases and combinations of load cases are added to the calculations.
8. New features within the framework of topological optimization of structures:
   - “irrelevant” items are hidden in the calculation settings tree. Depending on the selected item, the program will show the user only the required set of customizable parameters;
   - Added the ability to save stresses during calculations;
   - It is possible to start the calculation from the current field of volume fractions (volume fractions are converted into design variables);
   - “Restart” of calculation;
   - Added “responses-indicators” that allow you to evaluate the characteristics of the model without introducing additional restrictions into the task;
   - Accounting for special communication elements has been implemented: “rigid”, “deformable”;
   - It is now possible to limit the internal force in any type of elements available for topological optimization;
   - Added the ability to take into account “non-strict symmetry”, which will be implemented by the program only in the design space;
   - Added “non-strict” (aggressive) compliance with voltage restrictions, which in some cases allows you to obtain a wider range of solutions;
   - New technological limitation – “Milling”. At the moment, there is only a restriction on the minimum hole diameter;
   - Improved technological limitation “Stamping”. A new, more stable method for taking into account stampability has been built in;
   - Ability to save and view what is happening in optimization during the calculation process (external utility, or ParaView).
   

1. SECTION: Post-processing
2. A new tool has been added for performing arithmetic operations with calculation results. Operations are performed on the basis of generated result tables (sampling/cutting of calculation results with parameters of interest to the user). These tables can also be visualized as color maps of the results. It is possible to export and import tables of results into text files.
3. A new object “Trajectory” has been added to the “Calculation model” tree. It stores an array of nodes selected by the user on the calculation model
   and forming a polyline.
4. A new type of results has been added - “Results by trajectory”. Using a trajectory previously constructed and selected by the user (see paragraph 23), a graph of the type of result of interest can be constructed.
5. Linearization of calculation results when using the Path Results tool.
6. A new object “Plane” has been added to the “Calculation model” tree. It can be set on the work area by 3 points (nodes), by the edge of an element, or
   by a reference point and a normal vector.
7. New options have been added for viewing results maps: results in the “Section”, as well as at a certain distance from the selected section plane. The initial binding of the section occurs to some plane previously created by the user (see paragraph 26).  
8. A special “batch” mode for launching calculations (batch) has been implemented. Allows you to perform calculations sequentially for several files. Each file/model can have its own calculation settings and selected load cases for calculation. The user also sets priority settings that will take precedence over those saved in the model (preparing the file manually in a text editor). There is an optional opportunity to verify the calculation results.
