The latest updates to Itasca software products such as FLAC3D, FLAC2D, 3DEC, PFC, and MassFlow now introduce point-releases (e.g., 9.1, 9.2) between major versions (e.g., 9.0, 10.0). These point-releases bring significant benefits, especially for subscription license holders.
Subscription license holders enjoy seamless access to point-releases at no additional cost. These point-releases are packed with new features and capabilities developed in response to user feedback and industry advancements. By staying current with point-releases, subscribers can leverage the latest tools and functionalities, enhancing their productivity, efficiency, and competitiveness.
Perpetual license holders also benefit from continuous support within their software version's support period. While they may not receive point-releases, they still qualify for bug fix updates and minor improvements, maintaining stability and reliability in their software environment.
Improved Multi-Process Modeling
Multi-process models contain two or more coupled or decoupled solutions (mechanical/static, fluid, dynamic, thermal, and creep). Significant improvements have been done to greatly simplify multi-process models in order to make such analyses much easier to learn and use. New features include:
- FISH, Python, and Table data between may now be retained between models using the new SKIP keyword when issuing a
MODEL NEWorMODEL RESTOREcommand. This can also be very useful when running a series of parametric models in order to analyze all the model results being recorded. - The
SOLVEcommand has been updated to solve one process at a time simplifies working with multi-process models. Processes no longer need to be setONorOFF. - The
SOLVE-FLUID(orSOLVE-THERMAL) command can be used for loosely coupled models. The fluid or thermal solution leads (over a set time period), followed by mechanical solution (until set convergence criteria), repeating until the solve criteria is met. - The
SOLVE-FLUID-DECOUPLEDcommand can be used to solve a decoupled fluid/mechanical problem, where each step solves for fluid time then solves mechanically to set convergence criteria.
Better Scripting
- Python can now access the built-in geometry logic (user-defined nodes, edges, faces, volumes, etc.).
- The contourpy Python library (for calculating contours of 2D quadrilateral grids) is now built-in.
And More
- Variable viscosity for joint flow can now be specified.
- Grouping operations are now faster.
- New Hoek-Brown curve fitting and plotting tool – then add these value as
PROPERTYcommands right into your model. - QT 6 user interface libraries have been updated:
- User interface appearance is improved on high-resolution monitors.
- No need to specify OpenGL Mode.
- By place an * at the start of a command, all related warning messages will be suppressed.
- New unified dialog to better manage license/key management (Itasca Software License Manager).
- New and updated mechanical and fluid flow examples.
